The elusive S2 state, the S1/S2 splitting, and the excimer states of the benzene dimer.
We observe the weak S0 → S2 transitions of the T-shaped benzene dimers (Bz)2 and (Bz-d6)2 about 250 cm(-1) and 220 cm(-1) above their respective S0 → S1 electronic origins using two-color resonant two-photon ionization spectroscopy. Spin-component scaled (SCS) second-order approximate coupled-cluster (CC2) calculations predict that for the tipped T-shaped geometry, the S0 → S2 electronic oscill...
متن کاملPseudoholomorphic punctured spheres in R×(S1×S2): Properties and existence
This is the first of at least two articles that describe the moduli spaces of pseudoholomorphic, multiply punctured spheres in R× (S1 × S2) as defined by a certain natural pair of almost complex structure and symplectic form. This article proves that all moduli space components are smooth manifolds. Necessary and sufficient conditions are also given for a collection of closed curves in S1 × S2 ...
متن کاملDegenerative Sacrolisthesis of S1-S2: A Case Report
INTRODUCTION Degenerative spondylolisthesis (DS) is usually seen at L4-L5 level and less frequently at L5-S1 level. This is a rare case report of spondylolisthesis of S1 over S2 with lumbarization of S1. Lumbarization of S1 is seen in just 1-2% of the population and to have spondylolisthesis in this segment is even rarer. The purpose is to report a rare case of DS at S1-S2 level. CASE REPORT ...
متن کاملOn the Homflypt Skein Module of S1 S2
Let k be a subring of the eld of rational functions in x; v; s which contains x 1 ; v 1 ; s 1. If M is an oriented 3-manifold, let S(M) denote the Hommypt skein module of M over k. This is the free k-module generated by isotopy classes of framed oriented links in M quotiented by the Hommypt skein relations: (1) x ?1 L + ? xL ? = (s ? s ?1)L 0 ; (2) L with a positive twist = (xv ?1)L; (3) L t O ...
متن کاملPseudoholomorphic punctured spheres in R× (S1 × S2): Moduli space parametrizations
This is the second of two articles that describe the moduli spaces of pseudoholomorphic, multiply punctured spheres in R × (S1 × S2) as defined by a certain natural pair of almost complex structure and symplectic form. The first article in this series described the local structure of the moduli spaces and gave existence theorems. This article describes a stratification of the moduli spaces and ...
