Bernard J, Al-Mogeeth A, Martin S, Montagne G, Joblin C, Dontot L, et al.
Phys Chem Chem Phys . 2021 Mar; 23(10):6017-6028. PMID: 33667290
In this paper, we present an experimental and theoretical study of the photo-dissociation of free-flying dimer radical cations of pyrene (C16H10)2+. Experimentally, the dimers were produced in the plasma of...

Joblin C, Dontot L, Garcia G, Spiegelman F, Rapacioli M, Nahon L, et al.
J Phys Chem Lett . 2017 Jul; 8(15):3697-3702. PMID: 28742357
We report the first experimental measurement of the near-threshold photoionization spectra of polycyclic aromatic hydrocarbon clusters made of pyrene CH and coronene CH, obtained using imaging photoelectron-photoion coincidence spectrometry with...

Calvo F, Pahl E, Schwerdtfeger P, Spiegelman F
J Chem Theory Comput . 2015 Nov; 8(2):639-48. PMID: 26596612
The stable structures and melting behavior of Hgn clusters, 2 ≤ n < 60, have been theoretically investigated using an updated diatomics-in-molecules (DIM) model initially proposed by Kitamura [Chem. Phys....

Masson A, Heitz M, Mestdagh J, Gaveau M, Poisson L, Spiegelman F
Phys Rev Lett . 2014 Oct; 113(12):123005. PMID: 25279627
We investigate, theoretically, the joint relaxation of orbital and structure in postexcitation dynamics of Rydberg states of cluster BaArN (N=250). Mixed quantum-classical dynamics is used to account for the nonadiabatic...

Ben Salem F, Ben El Hadj Rhouma M, Spiegelman F, Mestdagh J, Hochlaf M
J Chem Phys . 2012 Dec; 137(22):224310. PMID: 23249006
The electronic state properties of NaXe are investigated using ab initio methodologies and various pseudopotential approaches for comparison. The spectroscopic terms and dipole moments of the lowest electronic states up...

Masson A, Poisson L, Gaveau M, Soep B, Mestdagh J, Mazet V, et al.
J Chem Phys . 2010 Aug; 133(5):054307. PMID: 20707532
Ba(Ar)(approximately 750) clusters were generated by associating the supersonic expansion and the pick-up techniques. A femtosecond pump (266.3 nm)-probe (792 or 399.2 nm) experiment was performed to document the dynamics...

J Phys Chem A . 2010 Apr; 114(18):5846-54. PMID: 20394399
This paper presents an investigation of anharmonic effects in the IR spectra of [SiPAH](+) complexes by using Born-Oppenheimer molecular dynamics for a variety of PAHs ranging from naphthalene (C(10)H(8)) to...

J Chem Phys . 2008 Dec; 129(15):154305. PMID: 19045191
The combined effects of size and temperature on the stable structures of water clusters doped with one ammonium molecule have been investigated theoretically using an empirical potential and density-functional theory...

Ben El Hadj Rhouma M, Ben Lakhdar Z, Berriche H, Spiegelman F
J Chem Phys . 2006 Sep; 125(8):084315. PMID: 16965020
The 4s and 5s Rydberg excited states of NaAr(n)* clusters are investigated using a pseudopotential quantum-classical method. While NaAr(n) clusters in their ground state are known to be weakly bound...
