Paper Abstract

Stark level-crossing spectroscopy is a new application of pulsed, single-frequency lasers which accesses highly excited vibrational states in a polyatomic molecule. The fluores-cence lifetime of a single rovibrational level in the first excited electronic state (S1) is recorded as it is Stark tuned across highly excited states of the ground electronic state (S0). Resonantly enhanced nonradiative decay causes dips in the S1 lifetime as the S1 state passes through resonance with S0 states, permitting the highly excited So level structure to be mapped out. Stark level-crossing spectra of d2-formaldehyde are presented.
