[CP2K:7874] Re: Availability of MOLOPT basis sets

[Feng Lai]

Hi

I would appreciate it if you could share the optimised TZVP/TZV2P basis 
sets with me. My email address is laifeng... at gmail.com.  And i am quite 
sure that my input is the same as yours, so i am very confused about how to 
get the paramenters in CBS.
