Abstract

A method of supersonic beam combined with techniques of laser spectroscopy and simulations of spectra were employed to study interatomic potentials of Cd₂ and Zn₂ molecules. Total laser induced fluorescence was recorded after an excitation of Cd₂ using laser radiation in the range of 2200–2260 angstrom. The observed structures are interpreted as due to the transitions from u" = 0 in the ground X¹0_g⁺ state to vibrational levels below the potential barrier of the ¹1_u(5¹P₁) electronic state. Studies of Zn₂ consisted of simulations of excitation and fluorescence spectra recorded at the ¹0_u⁺(4¹P₁)–X¹0_g⁺ transition. In the simulations, both isotopic and rotational structures were taken into account.
