SUMMARY
As molecular size increases, obtaining well-resolved rotational spectra becomes increasingly difficult due to two primary factors: the energy levels of the molecules become more tightly packed, and larger molecules often exhibit significant vibrational modes that can mix with rotational modes. This mixing complicates the spectrum, leading to convoluted results. Additionally, transitioning larger molecules into a gaseous state poses practical challenges that hinder experimental analysis.
