High field Stark effects in diatomic hydrides Scarl, Ethan Adam


A LoSurdo discharge was used to apply electric fields of more than 300 kV/cm to water vapor, a mixture of cyanogen and hydrogen, and ammonia, permitting the observation of Stark effects in the optical spectra of the OK, CH, and NH molecules, respectively. These experiments yielded the following values of the molecular electric dipole moment in the ground vibrational states: [See Thesis for Equation]. The dipole moments of the X ²π states in both OH and OD were also evaluated for v=0, 1, and 2, and were found to decrease as a function of v.
