“…They are assigned to the νNH mode of the conformer A (Table 5). Compared to the νNH frequency for the solution in CCl 4 (3437 cm -1 ) the weak increase with CDCl 3 (3442 cm -1 ) implies a direct influence of this proton donor solvent on the hybridization state at the N1 nitrogen level (11). The down-shift of the νNH frequency to 3390 cm -1 with CD 3 CN results from a direct H-bond of H200 with the C≡N moiety of this solvent (N1-H200···N≡C).…”

“…Compared to CCl 4 the increase of the strength of the intramolecular (O1-H201···N3) bond in CDCl 3 is this time, connected to the interaction of chloroform on the N1 atom. This entails a change in the hybridization state on the N1 atom, also influencing the conjugated (N1-C2′-N3) system (11).…”
