Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film
Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...
متن کاملApplications of Laser Raman Spectroscopy
Raman spectroscopy has undergone a technical revolution during the last fifteen years. Following a brief introduction to the physical principles we present recent applications to materials of technological interest. Nearinfrared excitation, in particular, offers the ability to measure the Raman spectrum in the absence of undesired absorption and photoreactions. The combination of Raman spectros...
متن کاملTunable laser resonance raman spectroscopy of bacteriorhodopsin.
Bacteriorhodopsin is a rhodopsin-like protein found in the cell membrane of Halobacterium halobium. It shows an absorption maximum at 570 nm and, in the light, undergoes cyclic spectral changes which include a relatively long-lived complex absorbing maximally at 412 nm. Excitation profiles have been obtained with several laser frequencies for two vibrations in the resonance Raman spectrum of ba...
متن کاملHIGH RESOLUTION LASER SPECTROSCOPY IN COLD SUPERSONIC MOLECULAR BEAMS COOLING, REDUCTION OF DOPPLER WIDTH AND APPLICATION
The cooling of molecules during the adiabatic expansion of supersonic seeded molecular beams is reviewed and illustrated by the example of NO -molecules. The reduction of the Doppler width by collimation of the beam and the cooling to low rotational temperatures brings a significant simplification of the complex NO -absorption spectrum and allows its assignment. The measured rotational tem...
