Zusammenfassung The design and performance of an analog computer for molecular vibrations is described. The computer solves the differential equation of vibrating molecules ( S = − GFS ) and is able to calculate simultaneously all its normal freque

The calculation of force constants of a valence force field including interactions from molecular vibration frequencies is a problem which in general has no unique solution. Therefore a number of different potential functions, all of which are in agr

From the vibration frequencies of the molecules BF3, BCl3, BBr3, BJ3, BO33−, CO32−, NO3− und C(NH2)3+ the force constants of a valence force field are calculated using an electronic analog computer. The solutions are presented graphically. If a

The five in‐plane vibrational frequencies of X2CO molecules are used to determine nine independent force constants of a general quadratic force field.Instead of the usual arbitrary assumptions about the four supernumerary force constants (which fou

From the molecular frequencies of COH2 and COD2 several sets of valence force constants were calculated with an analog computer. The isotope effect is sufficient to determine all force constants of a harmonic potential to about ±0,2 mdyn/A.
