Spectroscopic signatures of bond-breaking internal rotation. I. Saddle point induced polyad breakdown With the input of order 10–20 000cm−1of vibrational energy, the hydrogen atoms in small gas-phase molecules such as HCN, HCP, and acetylene can unde... MP Jacobson,MS Child - 《Journal...
[6–8]. It is important to understand that the value ofDfor a given bond varies depending on other bonds present on both atoms. For example, the bond C–H requires 410 kJ/mol to be broken in C2H6, but requires 528 kJ/mol whenbroken from HCN. Similarly, a C–C bond in C2...

Irrespective of the method used, the hydrogen bond donor radius increases in the order HF < HCl < H2O < HBr < HCN < HCCH < H2S, but mostly lie between Pauling's covalent and van der Waals radii of H atom. Interestingly, the acceptor radii for A in AHD also increase in the same ...
