De vigtigste bestanddele af cedertræolie, herunder nogle isomerer α-cedren, β-cedren, thujopsen osv., blev adskilt ved GC/MS, og 19 forbindelser blev identificeret.
Four isomers formed by a gold atom attached to a pentacene molecule were investigated by density functional theory due to their potential applications in molecular electronics.
Fire isomerer dannet ved et guldatom bundet til et pentacenmolekyle blev undersøgt ved hjælp af densitetsfunktionel teori på grund af deres potentielle anvendelser i molekylær elektronik.
The isomer ratio of o-MNT to p-MNT,the degree of dinitration and the ratio of 2,6-DNT to 2,4-DNT have been investigated in the mononitration product of toluene by mixed acid.
Forholdet mellem isomererne af o-MNT til p-MNT, dinitrationsgraden og forholdet mellem 2,6-DNT til 2,4-DNT er blevet undersøgt i mononitreringsproduktet af toluen ved hjælp af blanding af syrer.
The isomers dostribution of ortho-and para-toluenesulfonamide are successfully determined by high performance liquidchromatography (HPLC) . The results are compared with ultraviolet-spectroscopy (UV).
Isomerfordelingen af ortho- og para-toluensulfonamid er med succes bestemt ved hjælp af high performance liquid chromatography (HPLC). Resultaterne sammenlignes med ultraviolet-spektroskopi (UV).
The system condition of chromatography separating 2,6—2,4—2,3— and 3,4—toluenediamine isomer and the test methods verifying purity for toluene-diamine reference materilas were studied by HPLC.
Systembetingelserne for kromatografi, der adskiller 2,6–2,4–2,3– og 3,4–toluendiamin-isomer, og testmetoderne til verifikation af renhed for toluendiamin-referencematerialer blev undersøgt ved hjælp af HPLC.
But pentane, C5H12, has 3 possible isomers and C6H14, known as hexane, has 5.
Men pentan, C5H12, har 3 mulige isomerer, og hexan, C6H14, har 5.
Kilde: Crash Course Comprehensive EditionThus, no isomers with alkynes. Phew. OK I'm done describing for the moment.
Derfor ingen isomerer med alkyner. Phew. OK, jeg er færdig med at beskrive i øjeblikket.
Kilde: Chemistry Crash CourseBut if the parts are different, it's possible to have two totally different isomers of the same compound.
Men hvis delene er forskellige, er det muligt at have to helt forskellige isomerer af det samme stof.
Kilde: Chemistry Crash CourseYou would have to break the pi bond, and thus, the entire molecule to rotate between isomers.
Du skulle bryde pi-bindingen og dermed hele molekylet for at kunne rotere mellem isomerer.
Kilde: Chemistry Crash CourseThese different structures for compounds that have the same molecular formula are called isomers.
Disse forskellige strukturer for forbindelser, der har den samme molekylformel, kaldes isomerer.
Kilde: Crash Course Comprehensive EditionSo the number of atoms is butane only allows for 2 isomers, n-butane and isobutane.
Så antallet af atomer er kun i butan tillader 2 isomerer, n-butan og isobutan.
Kilde: Crash Course Comprehensive EditionBut looking at this table of the number of possible isomers you could see that that escalated quickly.
Men ved at se på dette skema over antallet af mulige isomerer kan man se, at det eskalerede hurtigt.
Kilde: Crash Course Comprehensive EditionThe kinked configuration is called the" cis isomer" and the straight one is the trans isomer.
Den snoede konfiguration kaldes "cis-isomer", og den lige kaldes trans-isomer.
Kilde: Scishow Selected SeriesWell we know that they're unsaturated alkenes because saturated fats don't have double bonds, and thus, can't have cis- and trans- isomers.
Ja, vi ved, at de er umættede alkener, fordi mættede fedtsyrer ikke har dobbeltbindinger og derfor ikke kan have cis- og trans-isomerer.
Kilde: Chemistry Crash CourseThey're not structural isomers like n-butane and i-butane, instead, they're what we call cis-trans isomers.
De er ikke strukturisomerer som n-butan og i-butan, de er i stedet, hvad vi kalder cis-trans-isomerer.
