Driver T, Mountney M, Wang J, Ortmann L, Al-Haddad A, Berrah N, et al.
Nature . 2024 Aug; 632(8026):762-767. PMID: 39169246
The photoelectric effect is not truly instantaneous but exhibits attosecond delays that can reveal complex molecular dynamics. Sub-femtosecond-duration light pulses provide the requisite tools to resolve the dynamics of photoionization....

Hammerland D, Berglitsch T, Zhang P, Luu T, Ueda K, Lucchese R, et al.
Sci Adv . 2024 Mar; 10(13):eadl3810. PMID: 38536928
We experimentally and theoretically demonstrate that electron correlation can cause the bond-length sensitivity of a shape resonance to induce an unexpected vibrational state-dependent ionization delay in a nonresonant channel. This...

Howard A, Britton M, Streeter Z, Cheng C, Forbes R, Reynolds J, et al.
Commun Chem . 2023 Apr; 6(1):81. PMID: 37106058
Filming atomic motion within molecules is an active pursuit of molecular physics and quantum chemistry. A promising method is laser-induced Coulomb Explosion Imaging (CEI) where a laser pulse rapidly ionizes...

Larsen K, Bello R, Lucchese R, McCurdy C, Slaughter D, Weber T
J Chem Phys . 2023 Jan; 158(2):024303. PMID: 36641397
We present an experimental and theoretical energy- and angle-resolved investigation on the non-dissociative photoionization dynamics of near-resonant, one-color, two-photon, single valence ionization of neutral O molecules. Using 9.3 eV femtosecond...

Severt T, Streeter Z, Iskandar W, Larsen K, Gatton A, Trabert D, et al.
Nat Commun . 2022 Sep; 13(1):5146. PMID: 36050308
The double photoionization of a molecule by one photon ejects two electrons and typically creates an unstable dication. Observing the subsequent fragmentation products in coincidence can reveal a surprisingly detailed...

Lin Y, Fidler A, Sandhu A, Lucchese R, McCurdy C, Leone S, et al.
Faraday Discuss . 2021 Feb; 228(0):537-554. PMID: 33595034
Multiple Rydberg series converging to the O2+c4Σ-u state, accessed by 20-25 eV extreme ultraviolet (XUV) light, serve as important model systems for the competition between nuclear dissociation and electronic autoionization....

Larsen K, Lucchese R, Slaughter D, Weber T
J Chem Phys . 2020 Jul; 153(2):021103. PMID: 32668943
We present a combined experimental and theoretical study on the photodissociation dynamics of ion-pair formation in O following resonant two-photon absorption of a 9.3 eV femtosecond pulse, where the resulting...

Fukuzawa H, Lucchese R, Liu X, Sakai K, Iwayama H, Nagaya K, et al.
J Chem Phys . 2019 May; 150(17):174306. PMID: 31067899
The molecular-frame photoelectron angular distributions (MFPADs) in O 1s photoemission from CO molecule were measured. Patterns due to photoelectron diffractions were observed in the MFPADs. The polarization-averaged MFPADs were compared...

Walton J, Rivera-Rivera L, Lucchese R, Bevan J
J Phys Chem A . 2019 Jan; 123(2):537-543. PMID: 30607945
A new force-based canonical approach for the accurate generation of multidimensional potential energy surfaces is demonstrated. Canonical transformations previously developed for diatomic molecules are used to construct accurate approximations to...

Walton J, Rivera-Rivera L, Lucchese R, Bevan J
Phys Chem Chem Phys . 2017 Jun; 19(24):15864-15869. PMID: 28589191
The concept of chemical bonding is normally presented and simplified through two models: the covalent bond and the ionic bond. Expansion of the ideal covalent and ionic models leads chemists...
