Description of spin-orbit coupling in excited states with two-component methods based on approximate coupled-cluster theory.

The Journal of chemical physics

Krause K, Klopper W.
PMID: 25770528
J Chem Phys. 2015 Mar 14;142(10):104109. doi: 10.1063/1.4908536.

A generalization of the approximated coupled-cluster singles and doubles method and the algebraic diagrammatic construction scheme up to second order to two-component spinors obtained from a relativistic Hartree-Fock calculation is reported. Computational results for zero-field splittings of atoms and...

Explicitly correlated ring-coupled-cluster-doubles theory.

The Journal of chemical physics

Hehn AS, Tew DP, Klopper W.
PMID: 26001446
J Chem Phys. 2015 May 21;142(19):194106. doi: 10.1063/1.4921256.

The connection between the random-phase approximation and the ring-coupled-cluster-doubles method bridges the gap between density-functional and wave-function theories and the importance of the random-phase approximation lies in both its broad applicability and this linking role in electronic-structure theory. In...

Density Functional Theory Study of the Formation of Naphthalene and Phenanthrene from Reactions of Phenyl with Vinyl- and Phenylacetylene.

Journal of chemical theory and computation

Aguilera-Iparraguirre J, Klopper W.
PMID: 26627160
J Chem Theory Comput. 2007 Jan;3(1):139-45. doi: 10.1021/ct600255u.

Reaction pathways for polycyclic aromatic hydrocarbon growth from reactions of either vinyl- or phenylacetylene with a phenyl radical are proposed and investigated using density functional theory (DFT). B3LYP/TZVP calculations are performed to obtain structures of minima and saddle points...

Demographics of attendees at public education seminars.

Headache

Klapper JA, Sheftell FD, Seawell M.
PMID: 11279951
Headache. 1999 Nov-Dec;39(10):752-3. doi: 10.1046/j.1526-4610.1999.3910752.x.

PURPOSE: The demographics of patients who attend public awareness seminars relating to headache have not been studied. In order to improve the presentations at these meetings, it was felt that the meeting planners should know as much as possible...

Insulin-Dependent Diabetes Mellitus: Islet Changes in Relation to Etiology and Pathogenesis.

Endocrine pathology

Kloppel G, Clemens A.
PMID: 12114788
Endocr Pathol. 1997;8(4):273-282. doi: 10.1007/BF02739929.

Type and type II diabetes are the most common types of diabetes. The ratio of type I to type II diabetes is about 1:9. Type I diabetes is caused by absolute insulin deficiency and is therefore referred to as...

Rhizobacteria-Mediated Growth Promotion of Tomato Leads to Protection Against Cucumber mosaic virus.

Phytopathology

Murphy JF, Reddy MS, Ryu CM, Kloepper JW, Li R.
PMID: 18944330
Phytopathology. 2003 Oct;93(10):1301-7. doi: 10.1094/PHYTO.2003.93.10.1301.

ABSTRACT We evaluated combinations of two strains of plant growth-promoting rhizobacteria (PGPR) formulated with the carrier chitosan for the ability to induce growth promotion of tomato plants and resistance to infection by Cucumber mosaic virus (CMV). Each PGPR combination...

Accurate computational determination of the binding energy of the SO3 x H2O complex.

The Journal of chemical physics

Fliegl H, Glöss A, Welz O, Olzmann M, Klopper W.
PMID: 16942218
J Chem Phys. 2006 Aug 07;125(5):054312. doi: 10.1063/1.2234372.

Reliable thermochemical data for the reaction SO3 + H2OSO3 x H2O (1a) are of crucial importance for an adequate modeling of the homogeneous H2SO4 formation in the atmosphere. We report on high-level quantum chemical calculations to predict the binding...

Analytic calculation of first-order molecular properties at the explicitly correlated second-order Moller-Plesset level: basis-set limits for the molecular quadrupole moments of BH and HF.

The Journal of chemical physics

Kordel E, Villani C, Klopper W.
PMID: 15974737
J Chem Phys. 2005 Jun 01;122(21):214306. doi: 10.1063/1.1924591.

The analytic calculation of first-order properties has been implemented in the DALTON program at the level of explicitly correlated second-order Moller-Plesset perturbation theory (MP2-R12). The implementation has been accomplished for MP2-R12 theory based on standard approximations A, A', and...

Accurate coupled cluster calculations of the reaction barrier heights of two CH3* + CH4 reactions.

J Phys Chem A. 2009 Oct 29;113(43):11679-84. doi: 10.1021/jp902753s.

We have computed barrier heights of 71.8 +/- 2.0 and 216.4 +/- 2.0 kJ mol(-1) for the reactions CH4 + CH3* --> CH3* + CH4 and CH4 + CH3* --> H* + C2H6, respectively, using explicitly correlated coupled cluster...
