Lithium concentrations [Li] and isotopic ratios [Li-7]/[Li-6] were measured for effluent fractions from a biphasic zeolite column. The biphasic state was ascribed to a mixture of hydrated Linde Type A (LTA) zeolite

Peroxyoxalate chemiluminescence (PO-CL) was investigated using eight oxalates with various phenol moieties and the distyrylbenzene (DSB) fluorophores with various substituents. The ρ-values in the Hammett correlation between the substituent constant

A graph theoretical index, here called a long-bond index (or a generalized Pauling bond order), predicts well the degree of electric conductance for (carbon sheet and carbon cylinder-shaped) molecular nano-structures. Some results are compared with t

物理化学の一分野である量子化学では，数学は化学の言葉そのものとなっている。化学における数学のもう一つの役割は「ツール」である。例えば，分布と誤差に関する離散数学は，現

This note first defines a class of cylindrical polyarenes polycyclic aromatic hydrocarbons (PAHs) C2(m+ 1)nH2n, for which the periphery is acenic. From this class the leapfrog algorithm derives the second class of cylindrical PAHs C6nmH4n, where the

Polarization-dependent optical properties of the open ( N , N ) carbon tubules C 4 N +2 Nn H 4 N ( N =5–8 and n =0–11) are studied in low energy region with the CNDO/S-TDA calculations. It is shown that the low-lying excitation energies periodica

The Pauling bond order can be viewed as a measure of the π-electron content of the respective carbon-carbon bond. In benzenoid hydrocarbons its values lie between 0 (in the case of essential single bonds) and 1 (in the case of essential double bonds

The semiempirical HAM/3 method developed by Lindholm and coworkers about two decades ago has been known to have a deficiency that splits energies for the degenerate energy states. We have recently proposed a group-theoretical approach to remedy the i

The concept of fully benzenoid hydrocarbons (molecular graphs; FBHs) is generalized. Each full-hexagon unit (aromatic sextet) in a FBH is replaced with a larger “hexagon-shaped” unit (subgraph; e.g., naphthalene, pyrene, coronene, or ovalene unit

A periodic n-dependence has been found in the lowest excitation energies of the tube-like fullerenes C60 + 10n (n=1,2,…), each consisting of a pair of the bisected caps of C60 and a single-wall cylinder. By inspection of the periodicity, the tube-l
