Abstract

The relative intensities of the lines in 26 of the stronger multiplets of the spectrum of normal titanium, Ti I, and in 8 of the stronger multiplets due to the singly ionized atom, Ti II, were measured by a general method of photographic photometry which is described in detail. In Ti , 58% of the multiplets were found to obey the intensity formulas to well within 5%, while in the 42% of abnormal multiplets, 71% of the lines were found normal, with 16% abnormally weak and 13% abnormally strong. In Ti II, 62% of the multiplets measured were normal, while of the abnormal 38%, 61% of the lines were normal, with 21% abnormally weak and 18% abnormally strong. Of all the lines measured, 86% appeared normal in intensity, while 7.6% were too weak and 6.4% were too strong. The departures from the predicted intensities are often fairly large, generally being of the order of 10% to 40%. No definite correlation was found between intensity abnormalities and depatures from Lande’s interval rule or the normal Zeeman patterns.
