Spectroscopic and thermoanalytical characterization of standard substances for the identification of reaction products on iron electrodes
TL;DR: In this paper, the in situ spectroscopic investigation of electrochemical, and especially corrosion processes in iron requires well-characterized reference substances, and it has been found that the application of spectroscopy methods alone is not sufficient for the detection of impurities in certain phases.

The Normal Vibrations of Polyatomic Molecules as Treated by Urey‐Bradley Field
TL;DR: In this article, a method of setting up the vibrational secular equation for polyatomic molecules of ''Urey-Bradley field'' type is described, and 102 fundamental frequencies calculated using 28 distinct force constants are in satisfactory agreement with the observed, with a mean deviation of 1.4 percent.

Infrared spectroscopic study on the co-ordination bond-I: Infrared spectra of cobalt hexammine, pentammine and trans-tetraammine complexes
TL;DR: In this article, the infrared spectra of [Co(NH3)6]3+, [Co[NH3]5X]2+ (X=F, Cl, Br and I), and trans[Co[Co( NH3]4X2]- (X =Cl, Br, I) have been measured in the 4000-250 cm−1 region and the observed frequencies were quantitatively assigned on the basis of the potential energy distribution and L- matrix.
