The unstable HBS molecule has been produced in the gas phase by a high-temperature reaction between crystalline boron and hydrogen sulfide. Ground state rotational spectra have been observed in the millimeter-wave region, from 75 to 460 GHz, for the previously unobserved H 11 B 33 S and H 10 B 33 S

## Abstract NMR nutation and quadrupole echo experiments were used to determine the quadrupole frequency (Ο~Q~) of ^87^Rb (__I__ = 3/2) in a single crystal of RbCaF~3~. Since RbCaF~3~ has a cubic unit cell above 195 K, there is no secondβorder quadrupole shift and the spectrum is rather featureless
Using a self-consistent NMR method, it is now possible to determine both the deuterium quadrupole coupling constant as well as the rotational dynamic isotope effect in liquids. We successfully tested the method on benzene for temperatures between 280 K and 293 K. The average value of 185(3) kHz for
