Comparison of intrinsic, solvational, and enzymatic rates of β-lactam ring opening allows rate enhancement due to specific enzyme interactions with given β-lactam moieties to be identified and modeled. Enzymatic rates of β-lactam ring opening may

The He I photoelectron spectra of 4,4′-(di-X)-2,2′-bipyridines [X = H, Cl, CH3, N(CH3)2] are reported. The low-energy regions of the spectra arising from orbitals which correlate with the a2(π), a1(nN) and b1(π) orbitals of pyridine are assigne

The saddle point for the proton transfer involved in the equilibrium 2-hydroxypyridine α 2-pyridone has been calculated in a 3-21G basis to be 206 kJ mol −1 above the lactim form, for a unimolecular mechanism. This barrier is estimated to be reduc
