Abstract Below 28 C the IR spectrum of N-methylquinuclidinium chloride shows the characteristic absorptions of a C 2h (H 2 O· Cl−) 2 planar cluster; however, above this temperature this spectrum is replaced with an entirely different spectrum tentatively assigned to extended “linear” hydrogen bonding. The bromide and iodide show only the linear type of IR spectra. Dissociation vapor pressure measurements of the low temperature form of the ...
