Nettet23. sep. 2024 · According to the Watson-Crick model, the double helix of DNA is assembled and stabilized by hydrogen pairing between matching “bases”. The hydrogen bonds are formed between the oxygen atoms (red) and the adjacent N—H bonds, and between the central nitrogen (blue) and the adjacent N—H bond. Nettet20. mar. 1999 · A systematic investigation of the occurrence of dihydrogen bonds in the main group elements is taken up. The complexes of LiH, BH 3, and AlH 3 with the third-row hydrides, viz. HCl, H 2 S, and PH 3, as well as their dimers are studied at the ab initio MP2 level of theory and compared with the corresponding second-row hydrides.
