Constraining P and T violating forces with chiral molecules

Autor: Chaja Baruch, P. Bryan Changala, Yuval Shagam, Yotam Soreq

Publikováno v: Physical Review Research, Vol 6, Iss 4, p 043115 (2024)

New sources of parity and time-reversal violation are predicted by well motivated extensions of the Standard Model and can be effectively probed by precision spectroscopy of atoms and molecules. Chiral molecules have distinguished enantiomers which a

Publikováno v: The Astrophysical Journal, Vol 948, Iss 2, p 133 (2023)

We report the detection of the lowest-energy conformer of E -1-cyano-1,3-butadiene ( E -1- ${{\rm{C}}}_{4}{{\rm{H}}}_{5}\mathrm{CN}$ ), a linear isomer of pyridine, using the fourth data reduction of the GBT Observations of TMC-1: Hunting for Aromati

Collision-Induced C_{60} Rovibrational Relaxation Probed by State-Resolved Nonlinear Spectroscopy

Autor: Lee R. Liu, P. Bryan Changala, Marissa L. Weichman, Qizhong Liang, Jutta Toscano, Jacek Kłos, Svetlana Kotochigova, David J. Nesbitt, Jun Ye

Publikováno v: PRX Quantum, Vol 3, Iss 3, p 030332 (2022)

Quantum state-resolved spectroscopy was recently achieved for C_{60} molecules when cooled by buffer gas collisions and probed with a midinfrared frequency comb. This rovibrational quantum state resolution for the largest molecule on record is facili

Ring-Opening Dynamics of the Cyclopropyl Radical and Cation: the Transition State Nature of the Cyclopropyl Cation

Autor: Nadav Genossar, P. Bryan Changala, Bérenger Gans, Jean-Christophe Loison, Sebastian Hartweg, Marie-Aline Martin-Drumel, Gustavo A. Garcia, John F. Stanton, Branko Ruscic, Joshua H. Baraban

Publikováno v: Journal of the American Chemical Society. 144:18518-18525

We provide compelling experimental and theoretical evidence for the transition state nature of the cyclopropyl cation. Synchrotron photoionization spectroscopy employing coincidence techniques together with a novel simulation based on high-accuracy a

Detection of Interstellar $E$-1-cyano-1,3-butadiene in GOTHAM Observations of TMC-1

We report the detection of the lowest-energy conformer of E-1-cyano-1,3-butadiene (E-1- C 4 H 5 CN ), a linear isomer of pyridine, using the fourth data reduction of the GBT Observations of TMC-1: Hunting for Aromatic Molecules (GOTHAM) deep spectral

Discovery of Interstellar 2-Cyanoindene (2-C$_9$H$_7$CN) in GOTHAM Observations of TMC-1

Autor: Madelyn L. Sita, P. Bryan Changala, Ci Xue, Andrew M. Burkhardt, Christopher N. Shingledecker, Kin Long Kelvin Lee, Ryan A. Loomis, Emmanuel Momjian, Mark A. Siebert, Divita Gupta, Eric Herbst, Anthony J. Remijan, Michael C. McCarthy, Ilsa R. Cooke, Brett A. McGuire

We present laboratory rotational spectroscopy of five isomers of cyanoindene (2-, 4-, 5-, 6-, and 7-cyanoindene) using a cavity Fourier-transform microwave spectrometer operating between 6-40 GHz. Based on these measurements, we report the detection
