The Astrophysical Journal, 1898, Vol. 8 free pdf Excerpt from The Astrophysical Journal, 1898, Vol. 8 But the formula is a cumbersome one. I do not know how many coordinate numbers may be necessary for an ideal chemistry to indicate all the properties of any particular substance, especially to compute the wave-length of every line of its spectrum, but that eight or even six constants of the formula for a series should be independent of one another, I do not believe. However, as long as I lack all knowledge of general relations suitable to reduce the law of series into a simpler form, I shall decidedly prefer a formula which satisfies the observations by means of many constants to one which, with only three or four constants, is unable to represent the observations approximately within the limits of their mean errors. But unfortunately, not many spectra are rich enough in lines to permit the application of so cumbersome an apparatus of calculation, and at the same time not so complicated that it is impossible to separate their series. And of these only a few arc sufficiently well known. My knowledge of the literature of this special subject being rather small, the only data I have found which arc suitable for the calculation are the excellent measures of the carbon and cyanogen band-spectra by Messrs. Kayscr and Runge. On these I have tried my formula, and computed the constants for a considerable number of series, of which I now publish only the part concerning the third band of the carbon spectrum. For the spectrum of cyanogen a photograph of Mr. Rydberg's was measured at the Copenhagen Observatory while I was engaged upon the preliminary computations, and these new measures promise to be valuable supplements to the measures of Kayscr and Runge. The carbon band ought not to wait for the cyanogen, though it requires further measurements before its calculation can be terminated definitively.
