 Can anyone please tell me what is the purpose of a Dipole derivative unit
 vector? I am using Gaussview to analyze vibrational modes and I saw that
 function, but I am not sure for what this function is used.http://www.ccl.net/cgi-bin/ccl/send_ccl_messagehttp-:-//www.ccl.net/chemistry/sub_unsub.shtmlhttp-:-//www.ccl.net/spammers.txt
