CCL:G: Related Hyperpolazability



 Sent to CCL by: "anuj   tripathi" [tranuj,,gmail.com]
 Sir
 I am dealing with the calculation of third order hyperpolarizability using
 Gaussian Software. Now I am facing problem in conversion of Debye-Ang**3 to
 atomic unit (au), please suggest the factor needed to accomplish the task.
 Also guide me the proper keywords used to calculate Gamma(i.e. third order
 hyperpolarizability) for an organic molecule and how to analyze the output
 file.
 Further is there any relation between parallel and perpendicular
 hyperpolazibility?
 thanks
