✦ Synopsis

The second order Stark et-feet hns beer. demonstrated on the phosphorescence microwave double resonance (PMDR) signals ofp-benzoquinone in 1,4dibromobenzene host 2t 1.6 K. It is shown that possible estimates of the zero-field parameters of the higher triplet state mixed by the field with the lowest triplet state can be determined from the observed Stark shift of the zero-field triplet spin transitions. Furthermore, by using polarized microwaves in the double resonance experiments, and from the anisotropy of the Stark effect on the PhiDR signal, the direction of the transition moment to the state that is mixed by TAe field can also be determined.
