    Notes: A sample of poly(methyl methacrylate) (PMMA), of which the molecular weight was known from light-scattering measurements, was subjected to gel-perrneation-chromatographic analysis, and the resulting Weight versus log molecular weight (MW) plot was converted by suitable computation to a Number versus linear MW plot. This could then be compared directly with the matrix-assisted laser desorption ionization MW distribution results obtained for the same sample. The MW distributions obtained by the two methods were significantly different. Two explanations for the discrepancy are offered.

    Notes: 35Cl nuclear quadrupole resonance (NQR) was studied in 2,4-dichlorobenzyl alcohol (2,4-DCBA) and 2,6-dichlorobenzyl alcohol (2,6-DCBA). The NQR spectrum of 2,4-DCBA show four lines and that of 2,6-DCBA two lines. The temperature dependence of the NQR frequencies from 77 K up to the respective melting points was studied. An order-disorder transition was observed in 2,6-DCBA around 215 K. Torsional frequencies and their temperature coefficients were calculated using the temperature dependence of the NQR frequencies, and were compared with the laser Raman spectra obtained at room temperature.

    Notes: 13C signal assignments of 3-ethyl-1-methylindole (1), 1-methyl-3-phenylindole (3), 1,3-dimethyl-2-phenylindole (5), 1-methyl-2,3-diphenylindole (10), 1,5-dimethyl-2,3-diphenylindole (12), 7-methoxy-2,3-diphenylindole (13), 7-methoxy-4-methyl-2,3-diphenylindole (14) and 1-(7-methoxy-4-methyl-2,3-diphenyl-6-indolyl)-1-(7-methoxy-2,3-diphenyl-4-indolyl)methane (15) are reported. Contrary to an earlier report on monophenylindoles, the para carbons of the phenyl groups of 3, 5, 10 and 12-15 resonate at lower frequencies than their ortho carbons. The methoxy carbon at position 7 in 15 absorbs at a higher frequency than other similar carbons in 13-15 owing to steric inhibition to resonance.
