✦ Synopsis

The pi --> pi* and n --> 5s absorption spectra of selenoformaldehyde, CH2Se and CD2Se, are reported. Both spectra are diffuse. The pi --> pi* transition extends from 243 to 210 nm with an extensive Franck-Condon profile and intensity maximum estimated at 230 nm. The Rydberg n --> 5s transition is superimposed on the pi --> pi* system. While still diffuse, the system is less extensive and shows an intensity maximum at 235 nm. The corresponding Rydberg transition of the deuterated species is blue shifted by 140 cm-1. Copyright 1999 Academic Press.
