Q:

Usage of comma after `thank`

In the acknowledgment of a manuscript I have the following structure
(the reason for thanking A, B, C, D, E, F are different):
I wish to thank A and B for ..., C and D for ..., and E and F for ....
Isn't it better to put a comma after thank? I mean to write 
I wish to thank, A and B for ..., C and D for ..., and E and F for ....

A:

You must not use the comma after the verb thank. 
When there is a list of items after a verb, you don't use a comma before the first item.
