Abstract

The microwave spectrum of AsP 3 has been measured and assignments for three different vibrational states have been made. The symmetric top ΔJ = +1 transitions have been fit to obtain rotational constants, centrifugal distortion constants and quadrupole coupling strengths for the three vibrational states (I-III), B I = 2201.394(1) MHz, eQqaaI = 48.728(5) MHz, DJI = 0.2(3) kHz, DJKI = 0.5(1) kHz and σ I = 4 kHz, B II = 2192.26(1) MHz, eQqaaII = 48.62(4) MHz, B III = 2183.93(2) MHz, eQqaaIII = 48.53(4) MHz. The experimental vibration-rotation coupling constant, α(ν 4) = 9.20(3) MHz is compared with results from MP2/6-311G calculations. The excited states (II and III) are tentatively assigned to the ν 4 and 2ν 4 excited vibrational states.
