A simple prescription is given for defining internal coordinates of the bond stretching, bending, out-of-plane bending, and torsional types which yields a kinematically complete set of vibrational coordinates with no redundancies in acyclic molecules and with 6μ redundancies in cyclic molecules, where μ is the number…

A discussion is given of some recent experimental results on the fine structure of the X-ray absorption edges of solids. Recent work has shown the existence for many solids of a pronounced maximum (raie blanche) at the absorption edge. For K-absorption this may be due to one of two causes: (i) a high density of normal…
Fluorescence and phosphorescence spectra, phosphorescence lifetimes, and relative ratios of intensities of fluorescence to phosphorescence of the dibenzoylmethane derivatives of the trivalent ions of Al, Sc, Y, La, Gd, and Lu have been measured. The lifetimes and intensity ratios of the various compounds differ widely…

An empirical method of calculating mass absorption coefficients is given. Complete tables of constants are presented for calculating μ/ρ for all elements and for wave-lengths less than the K critical absorption wave-length. Partial tables give constants for wave-lengths between the L1 and M1 critical wave-lengths. Cal…
Es wird ein einfaches und sehr empfindliches Verfahren zur quantitativen Messung der Depolarisationsfähigkeit von Lösungen angegeben und seine Handhabung an Beispielen eines darauf aufgebauten Jodmeters erläutert, das einen der Konzentration proportionalen Ausschlag liefert. Es eignet sich u. a. auch besonders für die…
