✦ Synopsis


We have measured directly, with one laser shot, the picosecond relaxation times of Kodak Q-switch Loolymethlne) dyes at 1.06~ using crossed laser beams. This technique offers a simple efft~ctive methr~d of measuring relaxation lifetimes of both fluorescent and non-fluorescent species.

Direct measurements of scattering cross sections for NHs in well-defined quantum states are made using a molcrular beam maser spectrometer. Cross sections are compared for a pure inversion state with those for a coherent superposition state for scattering gases He, Ar, Nz, N20, NHa, CFgH and CHaCN.T
