Measurements have been made of the velocity and absorption of ordinary sound in liquid helium at frequencies of 2, 6 and 12 Mc/s, over the temperature range from the normal boiling-point down to 0-85° K. The accuracy of the velocity measurements has been increased above that reported in an earlier paper, and the temperature and frequency ranges of those measurements have been extended. Particular attention has been paid to the attenuation in the neighbourhood of the A-point and in the very low temperature region. The attenuation is found to be very high near the A-point and at low temperatures, and is proportional to w2 between 1-2°K and the A-point. At lower temperatures a change in the frequency dependence is observed, indicating the presence of a relaxation effect. The significance of these results is discussed in relation to a recent theory of Khalatnikov.

HFO and HClO (fluorosyl and chlorosyl hydrides) and isomeric molecules HOF and HOCl (hypofluorous and hypochlorous acids) have been studied theoretically. On the basis of nonempiracal quantum chemical calculations (MP2, MP4 and CCD/6-311G**) geometry, energy and vibrational characteristics are analyzed and it is concluded that there is a poor chance to observe formation of HFO. Possibly, bombardment of HF in a solid matrix by 16O could lead at very low temperature to HFO.
