CCL: Natural transition orbitals (NTOs ) analysis?



 Sent to CCL by: "Yi ming  Cheng" [honestcym::hotmail.com]
 Due to a need of more compact description of the excitation from TDDFT result I
 wonder how can I do the NTOs analysis just like the reference listed below?
 Thank you in advance and any suggestion would be very appreciated.
