Replacing Sp2 Hybridized Carbon Centers with Phosphorus
… synthesis of cations that distinctly feature a sp2 hybridized phosphorus atom and are principally inspired from classic carbon motifs. Firstly, we explore a synthetic route to a phosphorus analog of a [3]cumulene (R2C=C=C=CR2). We found our target phospha-cumulene, also known as an allenylidene …

Multiphoton ionization photoelectron spectroscopy of iodine-bearing molecules
… in the range of 10$\sp{12}$-10$\sp{13}$W/cm$\sp2$. For the parent molecules studied, we have observed that the atomic iodine photofragment is predominantly formed in the $\sp2$P$\sb{3/2}$ and $\sp2$P$\sb{1/2}$ spin-orbit terms of the atomic iodine ground state. Subsequent 5-photon ionization …

Multiphoton ionization of hydrogen iodide and molecular iodine using photoelectron spectroscopy
… valence states correlate with H($\sp1$S) + I($\sp2$P$\sb{3/2,1/2});$ And for I$\sb2,$ they correlate with I($\sp2$P$\sb{3/2,1/2})$ + I($\sp2$P$\sb{3/2,1/2}).$ As a result, ionization from the ground states of spin-orbit doublets $(\sp2$P$\sb{3/2,1/2})$ of atomic iodine is predominant in the …

Investigation of the Stereochemistry of the Methyl-to-Methylene Elimination in the Biosynthesis of Several Terpenes Through the Use of Chiral Methyl Labeled Compounds
The synthesis of (R)- (13-$\sp2$H, $\sp3$H) farnesyl diphosphate has been completed by methodology similar to that used for the synthesis of (R)- (9-$\sp2$H, $\sp3$H) geranyl diphosphate. Incubation of the radiolabeled farnesyl diphosphate with 5-epi-aristolochene synthase gave the ($\sp2$H, …
