The dispersion curves of lattice and internal vibrations for two kinds of n-dodecanoic acid crystals composed of the cis and trans configurations, respectively, are calculated in a low frequency range below 500 cm1. The entropy difference between the two kinds of crystal is estimated from the ...
What is the difference between trans fats and hydrogenated fats? What are the differences between saturated and unsaturated fats? List six (6) differences between frying fats, margarine, and salad oils? What is the difference between saturated fats and unsaturated fats? How does a low fat diet ...
Juchem et al [55] evaluated the effect of feeding Ca salts of PO or of a blend of linoleic and trans-octadecenoic fatty acids to pre- and postpartum dairy cows. Lactating cows fed the blend of unsaturated FA were 1.5 times more likely to be pregnant at 27 or 41 d after AI, comp...
Cis & Trans on Cyclic Compounds Ring structures or cyclic compounds can also exhibit cis/trans isomerism without the presence of a pi bond. Remember, substituents will be cis and trans if they arelockedin place. Pi bonds are one way to lock them in place. Rings are another matter. For e...
Cyclohexane is an organic compound which can show cis-trans isomerism when it has two or more substituents. The key difference between cis cyclohexane and trans cyclohexane is that cis cyclohexane has its substituents pointing to the same face of the ring whereas trans cyclohexane has its substitue...
The cis-trans energy difference of bi-1-cyclopropen-1-yl and the fluorosubstituted derivatives are studied by ab initio methods in order to establish the stability of the cis and trans diene isomers. T...doi:10.1007/BF00554160Ramn Mara Sosa...
The cis-trans energy difference of bi-1-cyclopropen-1-yl and the fluoro-substituted derivs. are studied by ab initio methods in order to establish the stability of the cis and trans diene isomers. The results of the ab initio method STO-3G points toward the trans bi-1-cyclopropen-1-yl...
