The numbers of chiral and achiral alkanes and monosubstituted alkanes [PDF]
Tetrahedron, 1976 Abstract Whereas the theory for the enumeration of the optical isomers of the lakyl radicals and the alkanes has long been understood, this is not the case for the corresponding archiral isomers. We present for the first time recurrence formulae for counting the number of archiral isomers of the alkyl radicals and the alkanes. For chiral and archiral

Photothermal Imaging of Transient and Steady State Convection Dynamics in Primary Alkanes
Liquids, 2023 This paper presents a photothermal spectroscopy technique that effectively images convective heat flow in molecular liquids resulting from localized laser-induced heating. The method combines aspects of thermal lensing and photothermal deflection. A high-

On the shear-thinning of alkanes
Tribology Letters, 2023 Abstract The approximate power-law dependence ofthe apparent viscosity of liquids on shear rate is of-ten argued to arise from a distribution of energy barri-ers. However, recent work on the Prandtl model, whichconsists of a point mass being dragged by a damped,harmonic spring past a sinusoidal potential, revealed asimilar dependence of the ...

Hyper-Wiener index and Laplacian spectrum [PDF]
Journal of the Serbian Chemical Society, 2003 The hyper-Wiener index WWW of a chemical tree T is defined as the sum of the product n1 n2 n3, over all pairs υ,ν of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects υ and ν, and n3 is the ...
