“…Various physical properties of the NF2 radical have been determined. Studies on the infrared spectrum (63, 64, 73), the ultraviolet spectrum (52, 72), the mass spectrum (23, 91), and the epr spectrum (22,40,42,64,78), as well as the group electronegativity (39), of the NF2 radical, have been determined. Some of the physical properties of tetrafluorohydrazine are presented in Table III.…”
