The microwave spectrum of trans-nitrosoethylene-15N (nitrosoethene) generated by pyrolysis of chloroacetaldehyde oxime-15N has been observed in the frequency range from 8.0 to 40.0 GHz.The rotational constants of the 15N species are determined to be A = 50390(201), B = 5057.00(3), and C = 4605.29(3) MHz.The rs-coordinates (a and b) of the nitrogen atom of trans-nitrosoethylene are determined to be 0.540(1) and 0.453 Anstroem, respectively.The three r0 structural parameters were fitted to four rotationalconstants (B and C) of the normal and 15N species.The bond length of r(C-N) and two bond angles of C=C-N and C-N=O obtained are 1.439(10) Angstroem, 117.1(10) deg, and 112.7(10) deg, respectively.The possible pyrolysis mechanism of chloroacetaldehyde oxime was discussed on the basis of detecting the three pyrolysates (CH2=CH-15NO, HC15N, and CH2=O) by microwave spectroscopy.
