The MgCH radical and its magnesium-25, carbon-13, and deuterated isotopologs have been isolated in low temperature neon matrices and examined by the matrix isolation electron spin resonance technique for the first time. The radicals were formed throu

Hyperpolarizable organic molecules are attracting interest for use in nonlinear optical devices. Some zwitterionic merocyanine chromophores with exceptionally high first hyperpolarizabilities have been synthesized that possess an electron donor moiet

The phosphorescence yield and decay kinetics of coronene in deoxygenated polymethylmethacrylate (PMMA) have been determined over the temperature range 77–300 K. At temperatures below ∼200 K the decays were close to single exponential (lifetime =

Magnetic circular dichroism (MCD) and absorption spectra are reported for the Q, RV, and IV band regions (6000−19000 cm-1) of lutetium bisphthalocyanine in poly(methyl methacrylate) films and Ar matrixes. Weak, temperature-independent MCD of the IV

Persistent spectral hole-burning in the Q-band region is reported for a concentrated (≈ 2 × 10 −2 mol l −1 ) matrix of copper phthalocyanine in solid Ar at 1.6 K. Hole-burning occurs with a quantum efficiency of ≈ 10 −6 and can be reversed
