1. PULSED VISIBLE/UV SPECTROSCOPY/ MOLECULAR DYNAMICS
(6-031, Prof. Robert W. Field)

This laboratory specializes in stimulated emission pumping (SEP), laser induced fluorescence (LIF), dispersed fluorescence (DF), and surface electron ejection by laser excited metastables (SEELEM) spectroscopy of singlet and triplet states of acetylene. This facility also has the capability of performing pulsed FM laser spectroscopy.
