✦ Synopsis

Abstract

In the framework of the Heitler‐London method, a method for determining the allowed molecular multiplets is proposed. The method is based on the connection of the total molecular spin with the permutation symmetry of the coordinate wave function and on the isomorphism of the molecular point group with a certain subgroup of the electron permutation group. The method does not depend on the approximation in which the molecular ions are considered.

## Abstract The conventional method of determining the picrates formed by the unsaturated hydrocarbons such as indene is the use of an aliquot of the solution of the recovered picrates in chloroform, another aliquot being used for the determination of the total picrates. The accuracy of these deter
