I agree…Too bad Bezos doesn’t. RIP @washingtonpost.com

To keep the cool stuff coming...here are the orbitals of this solid-state click reaction as a function of displacement along a terahertz normal mode. So cool!

This is a cool one! We realize that thermally-initiated solid-state reactions are driven by terahertz phonons. Love how straightforward and clean this story is - the paper basically wrote itself! Much more soon! @urochester.bsky.social @chemrxiv.org

Encoding Polymorphism by Incorporating Lattice Dynamics to Design Molecular Materials Polymorphism in molecular crystals arises from the interplay between conformational strain, intramolecular forces, and collective lattice dynamics, yet its control remains largely empirical. Here, we ...

Excited about this one! We leveraged our understanding of lattice dynamics and resulting polymorphic transformations to purposefully design dynamic molecular solids. Great team effort @lucacataz.bsky.social @urochester.bsky.social @chemrxiv.org

This paper is very cool - might be the coolest result of my career. We bent a flexible crystal, did some low-frequency confocal spectroscopy, and directly visualized intermolecular strain spectroscopically. @urochester.bsky.social @chemrxiv.org #THz #BendyCrystals

How does a referee comment that blasts authors for using AI for writing - without evidence beyond “I don’t like this paragraph” - get through to authors? How can such accusations of ethical misconduct be levied without proof?

Super not okay. Esp since I’m the one who wrote the paragraph…

Two emails this morning, back to back (literally), that we were selected to be featured on journal front covers for two recently-accepted articles.

A sign of a good day in front of me, or is this my total allotment of good things for the day? Stay tuned 😅

Anharmonic Vibrational States of Double-Well Potentials in the Solid State from DFT Calculations We introduce a general approach for the simulation of quantum vibrational states of (symmetric and asymmetric) double-well potentials in molecules and materials for thermodynamic and spectroscopic applications. The method involves solving the nuclear Schrödinger equation associated with a one-mode potential of the type V(Q) = aQ2 + bQ3 + cQ4 (with a < 0 and c > 0) and thus explicitly includes nuclear quantum effects. The potential, V(Q), is obtained from density functional theory (DFT) calculations performed at displaced nuclear configurations along the selected normal mode, Q. The strategy has been implemented into the Crystal electronic structure package and allows for (i) the use of many density functional approximations, including hybrid ones, and (ii) integration with a quasi-harmonic module. The method is applied to the spectroscopic characterization of soft lattice modes in two phases of the molecular crystal of thiourea: a low-temperature ferroelectric phase and a high-temperature paraelectric phase. Signature peaks associated with structural changes between the two phases are found in the terahertz region of the electromagnetic spectrum, which exhibit strong anharmonic character in their thermal evolution, as measured by temperature-dependent terahertz time-domain spectroscopy.

🚨 New Publication in @acs.org #JCTC 🚨 We have calculated vibrational freqs and intensities for double-welled potentials in the solid state, led by Davide Mitoli from Torino, and featuring @urochester.bsky.social graduate students Maria Petrov and Will Stoll. Great work!
