Laser-Induced Isotopic Effects in Titanium Resonance
Titanium isotope ratios have been measured by resonance ionization mass spectrometry (RIMS) with special emphasis on the nature of laserinduced isotopic selectivity. A pronounced wavelength dependence of even mass isotope ratios is caused by large nuclear volume effects near the magic neutron number 28 in T i . Optical isotope shifts, ranging from 0.07 to 0.21 cm-l, between T i and 4eTi were me...
متن کاملSpectrophotometric determination of distigmine bromide, cyclopentolate HCl, diaveridine HCl and tetrahydrozoline HCl via charge transfer complex formation with TCNQ and TCNE reagents
The purpose of this investigation was directed to propose sensitive, accurate and reproducible methods of analysis that can be applied to determine distigmine bromide (DTB), cyclopentolate hydrochloride (CPHC), diaveridine hydrochloride (DVHC) and tetrahydrozoline hydrochloride (THHC) drugs in pure form and pharmaceutical preparations via charge-transfer complex formation with 7,7,8,8-tetracyan...
متن کاملNear-resonant rotational energy transfer in HCl-H2 inelastic collisions.
We present a new four-dimensional (4D) potential energy surface for the HCl-H2 van der Waals system. Both molecules were treated as rigid rotors. Potential energy surface was obtained from electronic structure calculations using a coupled cluster with single, double, and perturbative triple excitations method. The four atoms were described using the augmented correlation-consistent quadruple ze...
متن کاملLaser tunnel ionization from multiple orbitals in HCl.
Tunneling, one of the most striking manifestations of quantum mechanics, influences the electronic structure of many molecules and solids and is responsible for radioactive decay. Much of the interaction of intense light pulses with matter commences with electrons tunneling from atoms or molecules to the continuum. Until recently, this starting point was assumed to be the highest occupied orbit...
