Classic banana

This interpretation of the properties exhibited by the major EO-active phases of NOBOW and the rest of the classic banana mesogens posits the existence of four supermolecular diastereomers, at least two of which, the antiferroelectric phases SmCsPA and ShiCaPa, must exist as separate wells on the... 

It has been shown by Watanabe and coworkers [34] that LC molecules in the 1,3-benzene bis[4-(4- -alkoxyphenyhminomethyl) benzoate] homologous series, known as classic banana LC molecules, exhibit spontaneous polarization and chirality despite the fact that these molecules themselves are achiral. More recently, a variety of new LC phases classified and designated as B-phases have been discovered and reported [35—37]. A classic banana LC molecule commonly contains a 1,3-phenylene central core and a... 

This alternative description follows from classical ideas and from a VB description utilizing hybrid orbitals. According to this description, a double bond is described as consisting of two bent bonds, sometimes called r bonds or banana bonds, formed by the overlap of... 

There are two classical approaches to bonding in cyclopropane namely the Walsh molecular orbital approach and the bent bonds or banana bonds of the Coulson-Mofiit model. 

The interaction of the bent banana bonds of the classical Coulson-Mofiit valence bond model of cyclopropane which uses methane-like sp hybrids and joins three units to form the alicyclic ring imply a resonance energy in cyclopropane of 69 kcalmol" Modern molecular orbital calculations (STO-3G) support an electron rich n system and an electron deficient cr-system for cyclopropane. 

Esters are formed when carboxylic acids and alcohols react together. The sweet-smelling compounds associated with ripeness of fruit such as pears, bananas, melons and pineapples are esters. A classic, simple ester is ethyl ethanoate, produced in the reaction between ethanol and ethanoic acid ... 

Short stack or silver dollar, blueberry or banana, pancakes are the classic and beloved weekend breakfast of champions.
