Dear Sirs and Madams :
Pardon me for this query. Maybe the answer is too well-known.
Could you give me references to searches done using crystallographic
databases of the following.
1. Contacts of a phenyl ring with a nearby acidic hydrogen hanging
   above the ring.
2. Contacts of an acidic H atom with a methyl group.
Thanks a lot!.....................................Shridhar Gadre
