## GOBI~lUNICATIONS up to IO mg of molybdenum(V1) (added as ammonium molybdate) could be present under these conditions but greater amounts gave a yellow colour at the end-point. Vanadium could be determined in the presence of manganese(I1) (Table ). Amounts up to 150 and zoo mg of potassium fluor
Two electronic bands arising from the tt + 2e and tt \* 3t2 transitions are observed in the region ==360 nm and ~250 nm in alkali halide crystals doped with CrzO;-. These bands split and also show well resolved fine structure at.77"K. The fme structure is explained on the hasis of vibrational freque
