Using pump-and-probe methods of laser spectroscopy, we observed several fluorescence and excitation bands with rotational structure of radiative transition between the A2∏ and X2∑+ states of the CdH molecule. Based on the study of time-resolution of the fluorescence, the radiative lifetime of τ0=59.5±2.3 ns for the A2∏ state, and the cross-section of (1.31±0.03)×10-15 cm2 for quenching the A2∏(v=0) state by Cd collisions; τ0=61.0±4.6 μs for the X2∑+ state and the cross-section of (1.1±0.1)×10-18 cm2 for CdH molecule dissociation by Cd collisions are estimated.
