Experimental and theoretical studies of the [3,3]-sigmatropic rearrangement of prenyl azides
(Royal Society of Chemistry, 2017-10)
[3,3]-Sigmatropic rearrangement of isoprenyl azides has been extensively investigated in an experimental and theoretical level. Prenylazides with different chain lengths and phenyl prenylazide have been synthesized. NMR ...
A theoretical and experimental study to unequivocal structural assignment of tetrahydroquinoline derivatives
(2013-06-24)
The tetrahydroquinoline derivatives can be easily synthesized through Povarov reaction and have several important biological activities. This work describes a comparative study for the unequivocal assignment of molecular ...
Basis sets applied to the theoretical study of the vibrational structure of hexaaquaaluminum(III) ion
(Elsevier B.V., 2004-01-23)
Gaussian basis sets were developed with the Generator Coordinate Hartree-Fock (GCHF) method for the atoms from H (14s), O (23s16p), and Al (29sl9p) in the ground state. These basis sets were then contracted to 3s (12,1,1), ...
Interaction, Diffusion, and Fertility Transition in Costa Rica: Quantitative and Qualitative Evidence
(1999)
This chapter examines the role played by diffusion through social interaction in the Costa Rican fertility transition. The literature about the causes of fertility transition has traditionally focused on the socio-economic ...
