So, I also check the literature, for water, using flexible SPC model, in Buckingham potential form How do I use the Buckingham potential form for flexible SPC model? rewriting the itp for water? Best XJ 在 2011年11月15日 下午12:12,xiaojing gong 写道: > Many thanks > > > 2011/11/15 Mark Abraham

Many thanks for reply. Another question, If I use Buckingham potential for CNT, and I want to simulate CNT and water, shall I also transfer the SPC.itp from LJ to Buckingham potential? The most important is how to transfer? I will appreciate it if you can give me any suggestions. Best XJ 2011/11
