摘要: The laser induced fluorescence (LIF) excitation spectrum of DCO ( 2A′← 2A′) has been investigated in a supersonic free jet expansion. Eleven vibrational bands including the origin band were observed energy range from 38600 to 42500 cm−1. intensities found decrease rapidly with increasing excitation state due fast predissociation. High resolution spectra recorded for (000), (001), (010) and (100) determine precise fundamental term energies rotational constants spin–rotation state. data used derive the following structural parameters (): r(D–C)=1.121(6) A, r(C–O)=1.371(1) A ∠(DCO)=105.1(2)°.
