The Raman spectra of oxygen with di β erent isotope compositions were investigated in the solid state and in argon and nitrogen matrices at 15 K. The fundamental vibration of the isotopomers 16O17O, 16O18O and 17O17O reveal a doublet of lines, each separated by 2.2 cm-1, in solid oxygen and in nitrog

The monocondensation product 2, which, in the case of the tert-butyl derivative could be detected 3'P-NMR-spectroscopically in the reaction solution at -90Β°C'21, cannot be observed during the synthesis of 3, apparently because of the drastic reaction conditions[51.
