- Infrared spectra were recorded on a Perkin-Elmer Model 1420 infrared spectrometer as thin films or nujol mulls. NMR spectra were obtained in CDC13, or Me2SO - d6 solutions, (CH3)4 Si internal standard, at 200 MHz with a Varian Gemini 200 spectrometer. All boiling points and melting points are uncorrected and melting points were recorded on a Fisher-Johns melting point apparatus.
