✦ Synopsis

Ah&&-From

the infrared spectra of some 75 polynuclear aromatic compounds it is concluded that the presence of 1, 2, 3 or 4 adjacent H atoms in one six-membered ring gives rise to strong ahsorptions in the frequency ranges of 900-860, 860-800, 810-760, and 770-735 cm-l; the names solo, duo, trio and quartet absorption are proposed for these bands respectively.

Much evidence has been provided for the presence of contact-term contribution to paramagnetic shifts induced by lanthanide shift reagents (1) in 'H, 13C, 14N, 19F, and 3'P NMR spectroscopy (2,3). Conspicuous effects of contact shifts (C.S .) have been observed in 13C NMR spectra of stronger Lewis ba
