Experimental CCS Values in PubChem (Q6705716)

The collection of experimental collision cross section (CCS) values from ion mobility experiments in PubChem, retrieved via the code developed here. "All_CCS_in_PubChem.csv" contains all CCS values extracted from PubChem (previous versions contained entries with no CIDs, current version has all entries mapped to CIDs). "All_CCS_in_PubChem_wInfo.csv" contains all CCS values, plus post-processing (splitting annotations, adducts and comments, adding chemical identifiers), but excludes all entries with no CID (and thus no structural information - not applicable in current version). Details how this file was produced are given here.
