The use of phthalocyanines and carbocyanines in laser applications is reviewed from the perspective of the known solution chemistry of these two families of dyes. The optical behavior of such dyes is found to show certain effects which correlate with

An EPR experiment on X-irradiated cyanoguanidine single crystals at −60°C and at room temperature indicates that the temperature-dependent fine broadening of the spectra is completely reversible over this temperature range. The experimental hyperf

An analysis of liquid state cross polarization in AXN spin systems is presented. A two‐level geometrical formalism derived from symmetry considerations provides a closed form description of the quantum dynamics for arbitrary N. A parallel discussio

The complex beat-modulated boron-11 free induction decay of pentaborane-9 is used as a test of the beat spectrum (BS) method for resolution enhancement in a spin system which contains several coupling constants and multiple chemical shifts. The publi

The free induction decay (FID) in a pulsed NMR experiment is in certain cases modulated by a low frequency beat whose characteristics are determined by the spin system. Selective Fourier transformation of the beat-modulated FID (BMFID) permits separa

Variable-temperature carbon-13 NMR spectroscopy was used to examine the curing reaction of DGEBPA with piperidine. An initial adduct was directly observed and the disappearance of monomer could be conveniently followed. Unreacted epoxide carbons were

The carbon-13 chemical shifts and carbon-fluorine coupling constants are reported for a series of trifluoromethyl derivatives. The chemical shifts occur between 78–129 ppm. A qualitative attempt was made to reveal the important factors determining
