Conformations and Intramolecular Hydrogen Bonds of a Series of Amino-alcohols

This paper discusses all the possible conformations and intramolecular hydrogen bonds of a series of amino-alcohols.The intramolecular hydrogen bonds have a substantial effect on the conformational stability of them.The most stable conformers is characterized by an OH…N intramolecular HB,and the next stable conformers by NH…O HB,while the less stable ones are those without HB.The strong intramolecular HB OH…N leading to the significantly lowered energy levels of the occupied lone-pair molecular orbitals were founded.And the temperature dependence of photoelectron spectra(PES) is interpreted
