The "a" in R134a is an indicator. There are two gases that are similar R134 and R134a. They both have the same chemical make up which is 2 hydrogen, 2 carbon and 4 fluorine. However in R134 all of the elements stay separated in a gaseous state. In R134a the elements combine together in different ways. Two hydrogens can be bonded with 4 fluorines or 2 carbons with 4 fluorines, etc. Lower case letters are the "organization" of the molecules and upper case letters are the different blends of the refridgerant.
