Values in cm-1. Where α = vibration – rotation interaction constant (α = alpha in the table) I = 16.8575/B gives the moment of inertia I, where B is in units of cm-1 and I has units of amu Angstroms 2 ...

IN the atomic absorption method of analysis, first described by Walsh1, the solution to be analysed is sprayed into a flame, and with a hollow-cathode lamp which emits the line spectrum of the ...

The absorption spectrum is consistent with both a dense “steam” atmosphere made up of 70 percent water, as well as a cloudy hydrogen atmosphere where the clouds would hide the absorption spectra.

WITH the continuous spectrum described by Lyman (Astrophysical Jour., 60, 1) as a background, and with hydrogen flowing through the receiver of the spectrograph, it was found possible to ...
