Abstract
We investigated the S-33 nuclear quadrupole coupling in the rotational spectrum of isothiazole in natural abundance by molecular beam Fourie r transform microwave spectroscopy. In addition the N-14 nuclear quadr upole coupling could be analyzed with high precision. We derived the r otational constants A = 8275.51880(80) MHz, B = 5767.06181(40) MHz, an d C = 3396.85702(36) MHz, quartic centrifugal distortion constants, an d the quadrupole coupling constants (chi aa)(S-33) = 8.7015(57) MHz, ( chi bb)(S-33) = -32.9696(60) MHz, (chi aa)(N-14) = 1.0732(47) MHz and (chi bb)(N-14) = -2.4753(46) MHz.
