Fine Structure in the Arc Spectra of Indium and Thallium

Narayan, A. L (Nature Publishing Group, 1931-10-17)

Indium.-The hyperfine structures of a few indium arc lines have been reported by Jackson1 and McLennan.2 Jackson observed that each of the lines l2S½-22P½ and is a quartet; while McLennan observed only three components. ...
Spectra of doubly and trebly ionised thallium

Narayan, A. L; Pattabhi, P; Rao, A. S (Nature Publishing Group, 1929-09-20)

CONTINUING our previous work on Tl II and Pb III, the spectra of Tl III and Tl IV have been under examination by us for some time past. A preliminary attempt, by the application of the X-ray doublet-laws, revealed a number ...
The second spark spectrum of lead

Rao, A. S; Narayan, A. L (Nature Publishing Group, 1929-11-23)

THE second spark spectrum of lead was recently analysed by K. R. Rao and ourselves; and a preliminary report of the series regularities discovered was published in a paper (Ind. J. Phy., vol. 2, pt. 4, pp. 468-476.) We ...
Spectrum of doubly ionised arsenic

Rao, A. S; Narayan, A. L (Nature Publishing Group, 1929-08-10)

THE deepest term of the separation of doubly ionised arsenic (As III) is 4p 2P1. The values of these doublet terms relative to 2G were reported in a recent paper (Ind. J. Phy., 5, 3, p. 3) to be 220, 221 cm.-1. It was found ...
Über das zweite Funkenspektrum des Bleies

Rao, A. S; Narayan, A. L (Verlag Von Julius Springer, Berlin, 1930-01)
A precision direct-reading spectrophotometer

Narayan, A. L; Ananthasubrahmanyam, C. K (Calcutta University Press, 1940-10)

The experimental errors inherent in photographic photometry are discussed and a direct reading spectrophotometer for the visible especially adapted to the study of line, contour and absorption and fluorescence spectra is ...
