MASS SPECTROMETRIC AND MATRIX INFRARED INVESTIGATIONS OF THE FORMATION OF GASEOUS POBr.

By reaction of mixtures of PBr//3 and O//2 with silver at about 1100 K, gaseous POBr is formed; this has been shown by mass spectrometric and infrared matrix measurements. The calculated values for the heat of formation and entropy are: DELTA H degree //2//9//8 (POBr) equals 10. 8 kJ/mol, S degree //2//9//8 (POBr) equals 292. 9 J/K multiplied by (times) mol. Based on the following three vibrational frequencies (1253. 0, 407. 1, and 253. 7 cm** minus **1) and some isotropic shifts (**1**60/**1**8O), approximate force constants have been calculated.
