<div>Dear all,</div>
<div> </div>
<div>Here i have some questions about how to specify the free rotors, the hindered rotors and harmonic oscillators in a molecule.</div>
<div>Take the propenol for example: CH3-CH=CHOH, how many free rotors hindered rotors and harmonic oscillators in this molecule?</div>
<div> </div>
<div>This question bothered me. So if you know, please please reply to me, or give me some recommendations.</div>
<div> </div>
<div>Thanks in advance.</div>
