Yarwood, John published the artcileInfrared studies on charge-transfer complexes. I. Comparison of the vibrational intensities of pyridine with those of pyridine-iodine chloride, Related Products of iodides-buliding-blocks, the publication is Transactions of the Faraday Society (1969), 65(4), 934-44, database is CAplus.
Integrated ir intensity measurements are reported for the vibrational fundamental bands of pyridine and of the pyridine-ICl charge-transfer complex in CHCl3 and benzene solutions An attempt has been made to interpret the large intensity changes which occur on complexation in terms of the charge-transfer model proposed by Mulliken. Intensity perturbations arise in addition to those expected for the “weak” complex approximation and several interesting anomalies in the intensity data are discussed.
Transactions of the Faraday Society published new progress about 6443-90-9. 6443-90-9 belongs to iodides-buliding-blocks, auxiliary class Pyridines, name is Pyridine Iodochloride complex, and the molecular formula is C11H10ClNO, Related Products of iodides-buliding-blocks.
