cmaphthol crystallizes with the same type of hydrogen bonded chain like planar zig-zag structure as other X-H.-.X \_ systems (X = F. Cl. Br, and sometimes 0). The intramolecular k = 0 splitting for v(O-H) motions of crnaphthol has been clearly observed in the infrared spectrum with polarized light o
## Abstract According to the density functional theory calculations, the X···H···N (XN, O) intramolecular bifurcated (three‐centered) hydrogen bond with one hydrogen donor and two hydrogen acceptors causes a significant decrease of the ^1h^__J__(N,H) and ^2h^__J__(N,N) coupling constants across th
