    Notes: [Auszug] F. RASETTI (Phys. Rev., 34, 367; 1929) has recently obtained accurate data on the Raman effect for gaseous hydrogen. From his data it is possible to calculate extremely precise values of B0 and B1. This is very fortunate, for it is now possible, from band spectra, ...

    Notes: [Auszug] THERE are now so many as thirteen band groups associated with carbon and its compounds. Some of these, such as the violet CN group, have been studied exhaustively, both empirically and upon the basis of the quantum theory. I have endeavoured to arrange in progressions and to assign vibrational ...

    Notes: [Auszug] IN a paper before the American Physical Society (Phys. Rev., 23, 294, Feb. 1924) and in a letter to NATURE (Nov. 1, 1924, vol. 114, p. 642), I gave a set of electronic energy levels for the neutral nitrogen molecule, based on an analysis of its band spectra. These levels were designated X, A, ...

    Notes: [Auszug] IN NATURE for March 3, p. 287, I directed attention to the desirability of obtaining new data on the value of e/m, from deflexion experiments or from the Zeeman effect. Dr. Harold D. Babcock, of the Mt. Wilson Observatory, has just finished a series of measurements on the value of ejm, ...

    Notes: [Auszug] PROF. M. N. SAHA and Mr. N. K. Sur, in an article which has just appeared in the Philosophical Magazine (48, 421, Sept. 1924), present a theory regarding the identity of active nitrogen which coincides in certain respects with that advanced by me last December, in a paper read before the ...

    Notes: [Auszug] IT is quite customary, at the present time, to use as the most probable value of e/m that derived by Paschen from spectroscopic data, as given by equations (12) and (13), page 272, and (15) and (16), page 275, of Sommerfeld's “Atombau, ” third edition. Taking Paschen's own estimate of the error ...

    Notes: [Auszug] IN a report1 presented some twenty months ago on the values of e, h and e/m, attention was directed to the numerous inconsistencies shown by the experimental data. More recent developments have resolved a number of these inconsistencies, and it now seems possible to reduce all ...

    Notes: [Auszug] I HAVE recently been studying the vibrational energy functions of molecules, in connexion with a recalculation of heats of dissociation, and have noticed that the equation given by Dieke and Babcock (Proc. Nat. Acad. Sci., 13, 670; 1927) for the upper level of the atmospheric bands of ...

    Notes: [Auszug] PROF. A. S. EDDINGTON has recently (Proc. Roy. Soc., A, 122, 358; Jan. 1929) deduced a theoretical value of 136 for the well-known ratio hc/2πe2. The reciprocal of this ratio is usually denoted ‘the fine-structure constant a.’ Without presuming in any way to judge the ...
