Electrostatics determine vibrational frequency shifts in hydrogen bonded complexes

The shifts in the acetylenic C–H stretching vibration in the C–H⋯X hydrogen-bonded complexes correlate with the electrostatic component of the stabilization energy.

Machine learning prediction of interaction energies in rigid water clusters

A new machine learning based approach combining support vector regression (SVR) and many body expansion (MBE) that can predict the interaction energies of water clusters with high accuracy (for decamers: 2.78% of QM estimates).

The nature of selenium hydrogen bonding: gas phase spectroscopy and quantum chemistry calculations

Charge transfer interactions, along with electrostatic and polarization interactions, are important for the strength of hydrogen bonding when poorly electronegative atoms act as hydrogen bond acceptors.

Singlet–triplet gaps in polyacenes: a delicate balance between dynamic and static correlations investigated by spin–flip methods

In this work, we use various spin–flip methods to benchmark the singlet triplet (ST) gaps of small polyacenes and show that the error in the ST gaps with respect to the experiment is small and does not increase appreciably with the system size.

Prediction of enhanced solvent-induced enantioselectivity for a ring opening with a bifurcating reaction path

A fully atomistic molecular dynamics simulation predicts enhance induction of enantiomeric excess in the products of a reaction with a bifurcating reaction coordinate, when run in a chiral solvent.

The 1,4-phenylenediisocyanide dimer: gas-phase properties and insights into organic self-assembled monolayers

Binding in the 1,4-phenylenediisocyanide dimer is significantly larger than in the benzene dimer and serves as a prototype for organic self-assembled monolayers.

About this collection

The PCCP Emerging Investigator Lectureship aims to recognize and support the significant contribution of early career researchers in physical chemistry, chemical physics and biophysical chemistry. The Lectureship is a platform for an early career physical chemist to showcase their research to the wider scientific community. This collection includes selected articles published by the PCCP  Emerging Investigator Lectureship winners.

Showcasing the 2018 PCCP Emerging Investigator Lectureship winner Professor Debashree Ghosh, Indian Association for the Cultivation of Science.

Professor Ghosh develops and applies accurate quantum chemical methods to understand the interaction between light and coupled bio-chromophores.  Electronic structure theory gives us unique tools to understand the energy states of the chromophores and their coupling to each other and therefore, gives us a glimpse into their photochemistry and photo-dynamics.

Previous Winners:

2017 winner - Professor Ryan P Steele, University of Utah 

2016 winnerDr David Glowacki, University of Bristol
