Collisional relaxation of vibrational states of SrOH with He at 2 K
New Journal of Physics, 2015 Vibrational relaxation of strontium monohydroxide (SrOH) molecules in collisions with helium (He) at 2 K is studied. We find the diffusion cross section of SrOH at 2.2 K to be ${{\sigma }_{{\rm d}}}=(5\pm 2)\times {{10}^{-14}}\;{\rm c}{{{\rm m}}^{2 ...

An Intramolecular Frustrated Lewis‐Pair Based on a Bismuth(III) Acid Site
ChemistryEurope, Volume 4, Issue 9, September 2026.Triflate ligands were the key for the design of a frustrated Lewis pair (FLP) that utilizes a soft bismuth(III) center as the Lewis acidic site. The acceptor properties are based on empty p orbitals generated through the ionic binding of the triflate anions to the Bi center.

Soil Contamination Around the Copper Smelter and the Use of Soil Microarthropods as Bioindicators
Land Degradation &Development, Volume 37, Issue 15, Page 11384-11403, September 2026.ABSTRACT Soil contamination from smelter emissions, including heavy metals (HM), rare earth elements (REEs), and sulfur, poses a significant threat to soil ecosystems. In the immediate vicinity of the Głogów Copper Smelter, HM concentrations were several times higher than in more distant forest stands.

On the fragmentation of furan molecule and its dependence on the laser wavelength [PDF]
, 2008 The fragmentation processes of the aromatic conjugated diene systems have been studied by many research groups [1–10]. Derrick et al. [1], have studied the electronic structure using photoelectron spectroscopy, where a number of highly excited Rydberg ...

High-Resolution Photoelectron Spectroscopy and ab initio Quantum Chemistry
CHIMIA, 2004 The resolution that can be achieved by photoelectron spectroscopy has been continually improved over the past 50 years and is now sufficiently high for the rovibronic energy level structure of polyatomic molecular cations to be measured accurately ...

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.
