phosphorinanes give rise to an ABXY pattern where Jax = Jan = JBx = 0. The particular ABXY system where JAY = JBx = 0 is studied to calculate the expression of the E,, Eg, Eg and El,, energylevels and the frequency of the transitions connected to these energy-levels. The relative sign of the 3Jp\_o-
