Abstract: The microwave spectrum of AsP3 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, =48.728(5)MHz, =0.2(3)kHz, =0.5(1)kHz and σ I =4kHz, B II =2192.26(1)MHz, =48.62(4)MHz, B III =2183.93(2)MHz, =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. [Copyright &y& Elsevier] |
