Quantum-State-Controlled Collisions of Ultracold Polyatomic Molecules
Physical Review XCollisions between ultracold calcium monohydroxide (CaOH) molecules are realized and studied. Inelastic collision rate constants are measured for CaOH prepared in ground and excited vibrational states, and the electric field dependence of these rates is ...

The onset of Coulomb explosions in polyatomic molecules
Rapid Communications in Mass Spectrometry, 1999 With the development of high intensity femtosecond lasers, the ionisation and dissociation dynamics of molecules has become an area of considerable interest. Using the technique of femtosecond laser mass spectrometry (FLMS), the molecules carbon disulphide, pyrimidine, toluene, cyclohexanone and benzaldehyde are studied with pulse widths of 50 fs in ...

A new Raman technique of superior spectral resolution [PDF]
, 1982 Raman-active vibrational modes are coherently excited by the transient stimulated Raman process. A subsequent delayed probe of relatively long duration interacts with the freely relaxing vibrations.

ChemSusChem, Volume 19, Issue 10, 27 May 2026.Indoles are promising N‐heterocyclic liquid organic hydrogen carriers. Here, we investigate the reaction pathways of (methyl)indole (de)hydrogenation over Pd catalysts using reaction experiments and computational modeling: we show that distinct intermediates are formed in hydrogenation versus dehydrogenation steps, and stereocenter evolution is ...

Vibrational-translational relaxation time spectroscopy of polyatomic molecules
, 1988 We report experimental studies of the frequency dependence of the vibrational-translational relaxation time of polyatomic molecules strongly excited by resonant laser radiation.

ChemistryEurope, Volume 4, Issue 5, May 2026.In this study, transition metal‐chelated NH‐bridged dimeric poly‐cyclodiphosphazanes were synthesized, which exhibited enhanced anion receptor abilities capable of binding to noncoordinative, polyatomic anions such PF6. These complexes are air‐ and moisture‐stable systems within the cyclodiphosphazane family which possess uncoordinated P(III) moieties ...

General features of the dissociative recombination of polyatomic molecules
EPJ Web of Conferences, 2015 We discuss some aspects of a simple expression for the low-energy dissociative recombination cross section that applies when the recombination process is dominated by the indirect mechanism. In most previous applications, this expression has been applied

Methods for Direct Laser Cooling of Polyatomic Molecules
, 2022 Molecules controlled at the single-quantum-state level offer wide-ranging applications spanning many of the frontiers of modern physics. Within the past decade, simple diatomic molecules have been brought under full quantum control both via assembly from

Ambidentate coordination in hydrogen bonded dimethyl sulfoxide, (CH3)2SOH3O+, and in dichlorobis(dimethyl sulfoxide) palladium(II) and platinum(II) solid solvates, by vibrational and sulfur K-edge X-ray absorption spectroscopy [PDF]
, 2009 The strongly hydrogen bonded species (CH3)(2)SO center dot center dot center dot H3O+ formed in concentrated hydrochloric acid displays a new low energy feature in its sulfur K-edge X-ray absorption near edge structure (XANES) spectrum.

Fluorine‐Free Lithium Battery Using Boron‐Based Salt and Glyme Solvent
Chemistry–Methods, Volume 6, Issue 5, May 2026.Fluorine‐free battery exploits lithium iron phosphate (LFP) cathode, polyethylene oxide (PEO) binder, and lithium bis(oxalate)borate (LiBOB) salt in glyme solvent. The electrolyte has excellent performances, while the PEO binder without organic solvents during electrode preparation enable LFP loading of 13.6 mg cm−2, and a capacity of ~160 mAh g−1 (2 ...
