The Spectra of Carbon Monoxide and Silicon Compounds

Abstract

A PAPER published by Prof. Hartley (Proc. Roy. Soc. vol. lxviii. pp. 109–112, March, 1901) reminds me of some observations on the spectra of the compounds of silicon with fluorine and hydrogen (SiFl₄ and SiH₄), made by me several years ago and published in Wiedemann's Annalen (vol. xxi. pp. 427–437, 1884). As they seem to be not without some interest, and a definite explanation of them has, so far as I know, not been given till now, I may be permitted to give here a short account of the principal contents of my little paper.
