The dipole moment of HOCl in v(OH)=4

Pulsed laser excitation and photofragment detection methods are used to observe the 17(0,17) <-- 16(1,16) pure rotational transition within the v(OH) = 4 vibrational state of (HOCl)-Cl-35. Microwave frequency and Stark effect measurements give v(0) = 27484.33(10) MHz and mu(b) = 1.562(9) D. The dependence of mu(b), which is approximately parallel to the OH bond, on the level of OH stretch excitation appears linear and is consistent with that of H2O over the same 0-14000 cm(-1) energy range.
