Hi Jiamu,
Different atoms have different nonbonded radii also�called van der Waals radii. So it is impossible that give a�definite�dsitance limit. �Meanwhile�fixed values cannot be given for�these atoms�because they depend on the measuring technique and the molecule. However, some useful are listed below: H-------1.2 C-------1.7 N-------1.5 O-------1.4 P-------1.9 Xiang Xu BIDMC Harvard Medical School [EMAIL PROTECTED] >> >> On Jan 15, 2007, at 16:21, Jiamu Du wrote: >> >> > Dear All: >> > Another question is that after I find the contact information, how >> > to define a dsitance limit commonly? >> > Which limit can be accepted? >> > Thanks. >> > >> > Jiamu Du >> > Key Laboratory of Proteomics >> > Institute of Biochemistry and Cell Biology Shanghai Institutes for >> > Biological Sciences >> > Chinese Academy of Sciences (CAS) >> >> > > > -- > Jiamu Du > Key Laboratory of Proteomics > Institute of Biochemistry and Cell Biology Shanghai Institutes for > Biological Sciences > Chinese Academy of Sciences (CAS) >
