In the gaseous phase, vibrational-, rotational- and translational-energy transfer between small molecules can be observed experimentally from time-dependent optical spectra. Populations in the ...

Spectroscopy is an experimentally non-invasive way of studying the electronic structure of a system in different environments and/or physico-chemical conditions to elucidate the system’s molecular ...

Infrared spectroscopy is a standard technique, which depends upon the interaction between infrared radiation and the vibrating dipole moments of molecules. Except for homonuclear diatomics and noble ...
