Spectroscopy of Cd-2 and Zn-2 molecules in free-jet supersonic beams: experimental and theoretical studies

摘要

A method of supersonic beam combined with techniques of laser spectroscopy and simulations of spectra were employed to study interatomic potentials of Cd-2 and Zn-2 molecules. Total laser induced fluorescence was recorded after an excitation of Cd-2 using laser radiation in the range of 2200-2260 angstrom. The observed structures are interpreted as due to the transitions from nu" = 0 in the ground X(1)0(g)(+) state to vibrational levels below the potential barrier of the (1)1(u)(5(1)P(1)) electronic state. Studies of Zn-2 consisted of simulations of excitation and fluorescence spectra recorded at the (1)0(u)(+)(4(1)P(1))-X(1)0(g)(+) transition. In the simulations, both isotopic and rotational structures were taken into account.
