Cover Picture: Substituent Position–Driven Modulation of Excited‐State Dynamics in Cyanoindole: Jet‐Cooled Spectroscopic and Theoretical Insights (BKCS 1/2026) by Ahreum Min, Hakseung Ryu, Jiwon Kim, Cheol Joo Moon, Myong Yong Choi
Abstract
The cover image illustrates how repositioning the cyano substitution site between 5‐CNI and 6‐CNI reshapes the π‐electron distribution. Side views of the HOMOs highlight the orbital phase, contrasting the electron density differences at the C5 and C6 positions. Furthermore, the R2PI spectra demonstrate how this single positional change leads to distinct excited‐state electronic character. Details are in the article by Ahreum Min, Hakseung Ryu, Jiwon Kim, Cheol Joo Moon, and Myong Yong Choi . image
