How else but by experiment........?

Explanation:

A chemist would routinely perform combustion analysis to get #%C,H,N#, this could be used to determine the #"empirical formula"#. A determination of molecular mass could then be attempted, and this then gives the #"molecular formula"#, which is a whole number multiple of the #"empirical formula"#. Given the molecular formula we might take melting points of the compounds and its derivatives, or use spectroscopic techniques, and get an idea of the connectivity.

Your question is less than specific, so if you want further details you will have to supply further information.
