The reaction of iodobistrifluoromethylphosphine, P(CF 3 ) 2 I, with atomic fluorine was studied by fast-flow ESR methods. The initial stage of the reaction is the abstraction of I by F, to form IF with a bimolecular rate constant of (1.0 ± 0.3) × 1

A laboratory computer interface with an electron spin resonance (ESR) spectrometer is reported, which permits operator control of the magnetic field through the computer. Two programs are described. In the first, the field is stepped and checked for

The effect of cavity loading during magnetic resonance absorption of the accuracy of analysis by electron spin resonance techniques is calculated. Large samples, which degrade the cavity Q-factor due to absorption of a large fraction of the incident

The reaction rate constant of the addition of atomic fluorine to excess PF 3 was determined by fast flow ESR measurements to be (8.6 ± 0.6) × 10 12 cm 3 mole −1 s −1 at 300 K. The stoichiometry of the overall reaction of F with PF 3 was 2:1. Fi

The design and performance of a set of concentric shim coils for use in an electron spin resonance spectrometer are described. These are particularly advantageous in magnets with wide gaps operating at high fields.
