| 摘 要： | 本文应用LCAO-MC-AM1方法研究了N-溴代丝氨酸在不同位置氢解离后形成数种可能结构,即(Ⅰ)HOCH_2CH(NH_2Br)COOH+],(Ⅱ)HOCH_2CH(NHBr) CO-OH,(Ⅲ)HOCH_2CH(NHBr)COO-],(Ⅳ)OCH_2CH(NHBr)COO2-],(Ⅴ)HOCH_2CHCH(NH_2Br)COO。结果表明:(1) N-Br键的形成仅对氨基的酸性有影响;(2) 结构Ⅲ是稳定结构,它对反应物的进一步离解起支配作用。

| Abstract: | Based on the LCAO-MO-AM1, several possible molecular structures that formed when H~+ dissociated in OH and COOH with N-Bromoserine have been studied. That given the formation of N-Br bond increses the acid of amino group and HOCH_2CH (NHBr) COO-] is more stable than others. |
