Quantum dynamics of C10H− in the interstellar medium: inelastic collisions with He and formation reaction from the HC10H/H− reactants
C10H− is the longest ever observed carbon-chain anion in a molecular cloud. It is here investigated to obtain from quantum treatments its rotational inelastic dynamics with He and its formation reaction from H−/HC10H as reagents.

Unraveling the structural origins of stimulated emission redshift in cyanine dye 1122C: a combined AIMD and machine learning study
1122C undergoes ultrafast trans–cis photoisomerization, but its excited-state dynamics remain unclear. AIMD reproduces the stimulated emission (SE) spectrum. Using machine learning, we identified structural deformations driving SE redshift.

The puzzle of high lifetime and low stabilization of HO3˙: rationalization and prediction
A crucial puzzle in atmospheric chemistry is the long lifetime of HO3˙ despite its low stabilization energy. Our calculations suggest that the solution to this puzzle is linked to the non-RRKM effect due to cis–trans isomerization.

Optical gaps of F-center defects in LiF using many-body methods
The optical gaps of surface and bulk F-center defects are investigated using an efficient single-pole many-body method. Surface defect exhibits a reduced optical gap versus bulk due to weaker confinement effects and enhanced lattice relaxation.

About this collection
Professor Narayanasami Sathyamurthy’s influence on theoretical chemistry research in India, particularly in chemical reaction dynamics, is profound and far-reaching. When he joined the Indian Institute of Technology (IIT) Kanpur in 1978, he was the sole researcher in this field in the country. Today, numerous research groups, many led by his former group members or their students, are conducting pioneering work on various aspects of chemical dynamics at top institutions across India. His scientific legacy is both deep and lasting, and he has played a pivotal role in shaping the landscape of theoretical and computational chemistry research in India.
This special collection in PCCP celebrates his distinguished career and showcases research in theoretical and computational chemistry focused on the structure and dynamics of chemical systems. Topics of interest include, but are not limited to:
- Molecular reaction dynamics (experimental, computational and theoretical work)
- Computational chemical dynamics
- Statistical mechanics of condensed matter and biomolecular systems
- Potential energy surfaces and free energy landscapes
- Electronic structure theory and computation
