We applied our pictorial approach using the fundamental concept of the Hückel molecular orbital theory to the population inversion in the multilevel systems by the straddling‐STIRAP (S‐STIRAP). We showed that the mechanism of the population inversion in the multilevel system may be easily understood by our approach. It is also shown that our approach is useful to understand that the condition required for the laser frequency in the delayed pulse sequence is different for the even‐ and odd‐level systems. © 2000 John Wiley & Sons, Inc.
