(1)H, (13)C, and (19)F NMR spectra were measured for the title N-nitrosamines. The observed unusually low N-Nrotationbarriers (12-15 kcal/mol) result from a significant deviation of the nitrosamino system from planarity. A pyramidal character of the amino nitrogen was confirmed by the X-ray crystal structures of two compounds and by bathochromic shifts of the n-pi absorption bands in the UV spectra
