remove the solvent using the rotary evaporator (RotoVap). This was a important step because if done insufficiently or incorrectly it would result in abnormal or lack of proper peaks in the IR spectral data analysis leading to an invalid conclusion/experiment. Based on the spectral data analysis on the primary flavoring component that was isolated, which shows significant peaks at ~3400, 2900-3000, 1715 and ~1500, the overall structure must contain a benzene ring with a no-conjugated aldehyde.
