Summary

Story summary

Density functional theory shows pentacene has different electronic properties in monoclinic and triclinic phases.
Orbital centroids shift by 1 to 4 picometers between the two phases, altering the zero-field splitting tensor.
Differences in D_ab eigenvalues reach up to 4 MHz, aligning with experimental frequency shifts.
The findings emphasize crystal structure as a driver of molecular orbital behavior and point to pentacene's potential in quantum sensing.

History

Historical Context

Density functional theory (DFT), established in the 1990s, transformed computational chemistry by enabling accurate modeling of electronic structures. Pioneered by Walter Kohn and Pierre Hohenberg, DFT has since facilitated advancements in quantum mechanics and materials science. Current research on pentacene's electronic properties illustrates DFT's ongoing relevance, particularly in developing applications for quantum sensing technologies.
