Abstract: | The He(I) photoelectron spectra of the gaseous metaborates of K, Rb, and Cs have been obtained using a modified high-temperature cylindrical-mirror electron spectrometer equipped with a resistance-heated sample oven. Attempts to acquire data for LiBO2 and NaBO2 were unsuccessful because of the high temperature required for volatilization (on the order of 1300–1400 K). The identities of the vapor-phase molecules were based on mass spectrometric and electron diffraction data. Spectral lines were assigned molecular-orbital origins through the use of MO calculations and by analogy with other compounds of similar type. |
