✦ Synopsis

Mixtures of N,O, and N,O, have been prepared from measured volumes of NO and 0,. Phase relationships in the system N,O,/N,O,, which depend on the composition of the samples and on the temperature, were studied by the Guinier technique and differential thermal analysis. Single crystals of phases A and B of N,O, were grown in situ on a diffractometer and studied at temperatures between -107 and -170°C by X-ray diffraction. The structure analysis of A-N,O, (tetragonal, space group c = 880.49(13) pm, Z = 32, R 1 = 0.051 for 1030 unique reflections) is hampered 1 4 , / ~.

## Abstract A general synthetic approach for the synthesis of ^15^N‐ and ^17^O‐doubly labelled pyrimidine nucleosides is described. The ^15^N isotopes in uridine and the ^17^O isotope in the urea‐derived carbonyl group of uridine and cytidine originate from (^15^N~2~)[^17^O]urea (5) which was synth
