Dear Prof. Nilsson,
I would like to analyze the hydrogen bond between lipid and peptide to compare with the literature. The criteria that they use is the hydrogen bond said to exist if donor -acceptor distance is < 2.5 angstrom and the donor-hydrogen..acceptor hydrogen bond form angle > 145 degree. to set that, I would say cuthb 2.5, but to set the angle I could not simply say cutha 145, correct? how could I reach that angle? thank you
