The infrared spectrum of the matrix produced by co-deposition of copper vapour with neat phosphine at 60 K showed new bands at c. 2245, 1057, 1005, 997, 593 and 512 cm-1. These bands shifted to 1635, 766, 742, 733, 450, 370 cm-1 when PD3 was used in place of PH3. When nickel or chromium were used in place of copper, new bands were observed at 2280, 1004 cm-1 and 2250, 1025 cm-1 respectively. The infrared spectrum of the matrix produced by co-deposition of copper vapour with a dilute mixture of phosphine in krypton at 12 K showed new bands at 2250, 970, 968 and 958 cm-1. Experiments involving variation of the PH3 : Kr ratio and replacement of PH3 by a 1 : 1 PH3/PD3 mixture suggest that the latter three bands are due to Cu(PH3)n with n = 1, 3 and 2 respectively.

Acetone Oxime

The infrared spectrum of (CD3)2C=N—OH was measured in solution down to liquid nitrogen temperature. As the temperature is lowered several new "associated bands" appear indicating the presence of species more highly associated than cyclic dimers or trimers.
