Tetramethylsilane yog organosilicon compound nrog cov mis Si (CH₃)₄. Nws yog qhov yooj yim tshaj plaws tetraorganosilane. Zoo li tag nrho cov silanes, TMS lub moj khaum yog tetrahedral. TMS yog lub tsev thaiv nyob rau hauv organometallic chemistry tab sis kuj pom siv nyob rau hauv ntau yam niche daim ntaub ntawv.
Vim li cas Tetramethylsilane siv hauv NMR?
Tetramethylsilane tau dhau los ua cov khoom siv sab hauv tsim rau 1 H NMR vim nws muaj zog, ntse resonance kab los ntawm nws 12 protons, nrog rau kev hloov tshuaj ntawm low resonance zaus txheeb ze rau yuav luag tag nrho lwm yam 1 H resonances. Yog li, qhov sib ntxiv ntawm TMS feem ntau tsis cuam tshuam nrog lwm cov resonances.
Puas yog Tetramethylsilane toxic?
Tetramethylsilane zoo li tsis muaj xim, me ntsis acidic volatile kua. Kev phom sij loj heev. Muaj tshuaj lom los ntawm kev noj tshuaj. Tawm pa taws thiab fumes thaum rhuab mus rau qhov kub thiab txias.
TMS siv rau cov tshuaj lom neeg li cas?
Tetramethylsilane (TMS): Siv los ua tshuaj hloov pauv hauv 1H-NMR thiab 13 C-NMR spectroscopy.
TMS sawv rau dab tsi?
Transcranial magnetic stimulation (TMS) yog cov txheej txheem tsis muaj kab mob uas siv cov hlau nplaum sib nqus los txhawb cov paj hlwb hauv lub hlwb kom txhim kho cov tsos mob ntawm kev nyuaj siab. TMS feem ntau yog siv thaum lwm yam kev kho mob kev nyuaj siab tsis tau zoo.
