Abstract

Fine structure levels in an external magnetic field and angular dependences of resonance magnetic fields on the direction of an external magnetic field were calculated for two axially symmetrical quintet dinitrenes with the zero-field splitting parameters D q = 0.260 cm−1, E q = 0.000 and D q = 0.243 cm−1, E q = 0.003 cm−1. The EPR spectra of such dinitrenes contained lines of only three xy transitions (xy 1, xy 2, and xy 4), two Δm s = ±2 transition lines between the W −2 and W 0 sublevels, and three additional lines from noncanonically oriented molecules whose magnetic axis Z made an angle of 12°–16° or 52°–54° with an external magnetic field.
