Ammoxidation of 3-picoline over V2O5/TiO2 (anatase) system. II. Characterisation of the catalysts by DTA, SEM, FTIR, ESR and oxygen and ammonia chemisorption
TL;DR: In this article, the FTIR spectra of the used catalysts are altogether different from those of the fresh catalysts suggesting that the active phase has been drastically modified during the course of the reaction.

Spectral and thermal studies for some transition metal complexes of bis(benzylthiocarbohydrazone) focusing on EPR study for Cu(II) and VO2
TL;DR: Electronic and magnetic data proposed the octahedral structure for all complexes under investigation, except VO(2+), is a square-pyramidal geometry and TG analysis for most complexes supports the absence of solvent molecules in or out the coordination sphere through the high thermal stability observed on the thermal curves for the investigated complexes.

Electron Spin Resonance in Transition Metal Chelates. I. Copper (II) Bis-Acetylacetonate
A. H. Maki,B. R. McGarvey +1 more
TL;DR: In this article, the parameters of the spin Hamiltonian have been expressed in terms of the atomic orbital coefficients of molecular orbital wave functions describing the electron hole in the orbital ground state and two excited states and the results indicate that the inplane sigma and pi bonding are appreciably covalent, whereas the out-of-plane pi bonding with the acetylacetonate ring is ionic.
