Abstract:

Sensitivity of microwave and infrared spectra to variation of fundamental constants is ypically higher, compared to optical and UV spectra. This is particularly important for astrophysical observations, where all lines are Doppler broadened. We will also discuss several variants of possible laboratory experiments with cold molecules.
