Natural hyperfine and magnetic predissociation of the I2 B state I. — Theory

Abstract

This paper analyses in detail the gyroscopic, hyperfine and magnetic predissociation phenomenon, and calculates the predissociation rate of molecular iodine. The peculiarities of very weak predissociations and of interference effects between predissociation are presented, and the experimental techniques available for that type of predissociation are discussed. This paper is the theoretical basis of the experimental studies of iodine B state predissociations which are described in the following two papers.
