Most of the extraordinary instrumentation so far developed for surface science studies is applicable only at solid/vacuum interfaces. We need comparable capability at the solid/liquid boundary, and we will gain it from fundamental research in solid state chemistry, electro- chemistry, surface analysis, and surface spectroscopy. Organic radicals are promising building blocks for molecular spintronics. Little is known about the role of unpaired electrons for electron transport at the single-molecule level. Here, we examine the impact of magnetic fields on electron transport in single oligo(p-phenyleneethynylene) (OPE)-based radical molecular junctions, which are formed with a mechanically controllable break Cited by:
Ultrafast mid-infrared (mid-IR) laser sources have recently attracted tremendous interest due to their promising applications in molecular spectroscopy, mid-IR supercontinuum generation, mid-IR frequency combs, material processing, laser surgery, biodiagnostics, etc. 1–3 1. by: 8. This book gives an overview of biological and medical applications of these laser pulses. The briefness of these laser pulses permits the tracing of the fastest processes in photo-active bio-systems, which is one focus of the book. The other focus is applications that rely on the high peak intensity of ultrashort laser pulses.

Geometrical structure of benzene and naphthalene: Ultrahigh-resolution laser spectroscopy and ab initio calculation August The Journal of Chemical Physics (5) We report high-resolution ( cm⁻¹) Fourier Transform Infrared spectra of fluoroform (CHF3) including the pure rotational (far infrared or THz) range (28–65 cm⁻¹), the ν3 fundamental.
Atomic and Molecular Spectroscopy is a wide-ranging review of modern spectroscopic techniques such as X-ray, photoelectron, optical and laser spectroscopy, and radiofrequency and microwave techniques.
On the fundamental side it focuses on physical principles and the impact of spectroscopy on our understanding of the building blocks of matter, while in the area of 5/5(1). Use of the sputtering vaporization technique allows high-resolution saturation spectroscopy to be readily extended to almost any element, including the highly refractory elements.
This chapter focuses on high-resolution pulsed laser spectroscopy in the UV/VUV spectral region. It offers advantages such as ultrahigh resolution cm The goals of atomic, molecular, and optical physics (AMO physics) are to elucidate the fundamental laws of physics, to understand the structure of matter and how matter evolves at the atomic and molecular levels, to understand light in all its manifestations, and to create new techniques and devices.
During the past 25 years, mid-infrared LAS techniques have become extremely sensitive, commercially available and effective spectroscopic tools from ~ 3 to 12 μm (it should be noted that Sb-based laser diodes, ICLs and QCLs spectral coverage from 2 to 24 μm has been demonstrated and reported in the literature (Belenky et al., ; Christensen et al., ; Curl Cited by: 8.
The infrared spectroscopy is a powerful technique to identify colorless quartz with potential for color development by irradiation and heating for jewelry. It is being routinely used in Brazil since In this chapter the use of FTIR for this purpose is described in detail.
Optical nanofibers have also been used in saturation absorption spectroscopy studies of acetylene (12 C 2 H 2) molecules in a chamber at Pa pressure. Passing an infrared (IR) pump beam through the nanofiber and retroreflecting it as a probe beam, the spectra of the P9 transition were obtained with a narrow saturated by: CONFERENCE PROCEEDINGS Papers Presentations Journals.

Atomistic level understanding of interaction of α,β-unsaturated carbonyls with late transition metals is a key prerequisite for rational design of new catalytic materials with the desired selectivity toward C═C or C═O bond hydrogenation.
The interaction of this class of compounds with transition metals was investigated on α,β-unsaturated ketone isophorone on Pd() as a Cited by: 6.

In this chapter, a brief overview of the most important fundamental knowledge required to perform absorption spectroscopy is described. As this paper does not intend to be a textbook on absorption spectroscopy, for a more in-depth description of the basics of absorption spectroscopy the reader is referred to various books [26, 29–31] and papers [12, 15, 32, 33].
Spontaneous Raman and infrared micro/spectroscopy can provide adequate chemical specificity and sensitivity to delineate a variety of neoplasms [,,] but require long integration times and have a coarse spatial resolution, which may limit accurate tumour-boundary identification and early-stage Cited by: 3.

Among far-field fluorescence microscopy techniques, confocal and multiphoton microscopy are among the most widely used to moderately enhance the spatial resolution (14, 15).By combining a focused laser for excitation and a pinhole for detection, confocal microscopy can, in principle, have a factor of √2 improvement in the spatial by:.
The XV International Conference on Laser Spectroscopy brought together spectroscopists from all over the world working in the very diverse and still growing field of laser spectroscopy. It addressed a large number of modern scientific issues at the highest level.Photoacoustic tomography (PAT) is an emerging imaging modality that shows great potential for preclinical research and clinical practice.
As a hybrid technique, PAT is based on the acoustic detection of optical absorption from either endogenous chromophores, such as oxy-hemoglobin and deoxy-hemoglobin, or exogenous contrast agents, such as organic dyes and by: Rather different problems can be lumped together under the general term 'laser control of atoms and molecules'.
They include the laser selection of atomic and molecular velocities for the purpose of Doppler-free spectroscopy, laser control of the position and velocity of atoms (i.e. laser trapping and cooling of atoms), and laser control of atomic and molecular processes (ionization.
