Short: How to get proton affinities for a large list of chemicals? A database? A programming API?
I have ca. 2000 chemicals (downloaded from MCM, mostly organics that occur in the atmosphere and their reaction products). I would like to try to get proton affinities for as many of the 2000 chemicals as possible.
I know how to look up the proton affinity for a chemical in the NIST Chemistry WebBook (for example isoprene). But I would prefer to get a machine readable database, or a Python API (or any programming language), to get these nicely in a program code.
What options do I have?
(I am not going to get 2000 values by hand, so my last option would be to write a small web scraper to make these 2000 web queries)
