Abstract

Abstract From the vibration frequencies of the molecules BF 3, BCl 3, BBr 3, BJ 3, BO 3 3−, CO 3 2−, NO 3 − und C(NH 2) 3 + the force constants of a valence force field are calculated using an electronic analog computer. The solutions are presented graphically. If available the frequencies of isotopic molecules are used to find a unique solution, but in the case of BBr 3 and BJ 3 the isotope effect is too small to be of any practical value, whereas for BF 3 and BCl 3, it is just sufficient to set rather broad limits for the true potential function of the molecules.
