Help on alternative terpene names and naming schemes
Chemical nomenclature is officially defined by IUPAC (International Union of Pure and Applied Chemistry). You can find most IUPAC names for these terpenic compounds by searching their popular names on Wikipedia, they are quite long and confusing terms though, and can only be interpreted if you have a certain knowledge in organic/inorganic chemistry.

What you are probably more interested in are databases with hundreds of thousands of compounds with unique identifying numbers that are unequivocally assigned to a specific substance. Two of the largest are CAS Index (https://en.wikipedia.org/wiki/CAS_Registry_Number) and ChemSpider (https://en.wikipedia.org/wiki/ChemSpider). I believe working with numbers will facilitate your work a lot, so I would suggest that you look for one of these databases (but be careful, each database uses a different numbering system so you should pick one and stick to it).
