Capture Method

The electron capture method was applied to protoporphyrin IX and meso- porphyrin IX dimethyl esters, metal-free phthalocyanine, chlorophyll, riboflavine, nicotinamide, tetracene, and pentacene. The energy quantities obtained correlated with calculated energies of the lowest empty molecular orbitals of these molecules.

Abstract A wall stabilized low-current cylindric arc was used to produce the radiation of the negative Bromine-ions. The radiation consists of an affinity-continuum with a long-wave threshold of 3682 Å, yielding an electron affinity for Bromine of 3.366 eV, and of an intense electron-atom Bremsstrahlung in the visible. Intensity measurements of the continua allow the determination of the photo-detachment-and attachment-cross-sections of Bromine and also the determination of the mean elastic cross-section of electrons against Bromine atoms.
