Full Linear Search and Maximum Rotation Gradient

[Pang Siu Kwong <pang ^at^ iris.chem.cuhk.edu.hk>]

 Hello!  In Guaussian 94, there are three techniques, SD, SSD and QC, for
 convergence. How does the "Full Linear Search" affect the convergence
 when
 using these techniques?  If the convergence problem encounters, does the
 "Full Linear Search" help? Furthermore, how does the Maximum Rotation
 Gradient affect the QC?  If the convergence problem encounters,
 does change the value of "Maximum Rotation Gradient" for solving this
 problem?
 Thank your for your attention.
