I would like to know if a commas could change the reference of "which"?
For example does the word "which" in the sentence below refer to the argon laser or to the orange complex?
Spectral data of the complex that is formed between Ruhemannís purple and zinc chloride were also reported in the same work. The 488nm line of the argon laser was found ideal for excitation of the orange complex, which absorbs at about 485 nm and emits at 560 nm.
I'd say it refers to the nearest antecedent: the orange complex.
