The Urey — Bradley Force Constants of Trigonal Bipyramidal XY5 -Type Moleculesl., and PF. using the Urey—Bradley force field. It has been found that the introduction of an angle—angle interaction force constant to the simple Urey—Bradley force field is necessary to obtain good agreement between calculated and observed frequencies. The results provide consistent band assignmen

Mutual Interference Effects of Certain Group III-A Ions with Calcium in Flame Spectroscopyfect, i.e., the effect of calcium on emissions of Group III-A elements also has been determined. Sample dilution decreased BO.. suppression but increased Al. suppression of calcium radiations. Apparently n-butanol forms a compound with the BO.. ion in the evaporating aerosol droplet. This results in

The combined use of these two tools holds unique advantages and is certain to be employed even more frequently in the analytical and research laboratories.
