Testing the morphed potential of Ar:HBr using frequency and phase stabilized FASSST with a supersonic jet Academic Article uri icon


  • The lowest frequency bending vibration of Ar:HBr has been recorded using frequency and phase stabilized Fast Scan Submillimeter Spectroscopic Technique (FASSST) coaxially with a supersonic jet. The fitted band origin was 0 = 329611.4482(16) MHz, the excited stated rotational constant was B = 1236.41359(22) MHz, the distortion constants were DJ = 0.0124740(36) MHz and HJ = -2.503(17) 10-6 MHz and the quadrupole constants were aa = 260.9552(79) MHz and D = -0.03174(35) MHz for Ar:H79Br. Corresponding values have also been determined for the Ar:H81Br isotopomer. aa and D are compared with values predicted from a recently determined morphed potential of Ar:HBr. 2003 Elsevier Science B.V.
