The nozzle temperature was 24…25 °C.
a
) Uncertainties were unidentified, possibly estimated standard errors.
) Differences between similar parameters were
restrained to the values from MP2/6-31G* calculations.
c
) Difference between the O–N and N–C bond lengths
was restrained to the value from MP2/6-31G* calculations.
d
) Restrained to the value from MP2/6-31G* calculations.
e
) Torsional angle C–Si–C–H, τ1 = 0° for the syn position.
f
) Torsional angle C–N–C–H, τ2 = 0° for the syn position.
