New Method for Photoelectron Spectroscopy of Solutions.
Abstract
A new method of rather general scope is reported for the determination of the photoionization (PI) spectra of solutions. Spectra thus obtained correspond to PI for ejection of quasifree electrons into the liquid phase. The method is based upon photoelectron emission (PEE) into vacuum by the solution upon irradiation with adjustable photon energy. A new instrument is described which features irradiation (up to 10 eV) of a film of the solution on the rim of a rotating disk target (72 r.p.m.). Two types of data are obtained: PEE quantum yield per incident photon as a function of photon energy; energy distribution curve (EDC) of electrons emitted into vacuum at given photon energies. The PI cross section is obtained as a function of photon energy by the previously developed method of EDC superposition. The method is applicable even when the contribution by the solvent to total PEE is dominant. Application is made to PI by 0.4 M indole in glycol for irradiation from 6.5 to 10 eV.
