Nidaamka Tijaabada LADP-1A ee CW NMR - Qaabka Horumarsan Sawirka Lagu Soo Bandhigay

Nidaamka Tijaabada LADP-1A ee CW NMR - Qaabka Sare

Sharaxaad Gaaban:

Resonance magnetic nuclear (NMR) waa nooc ka mid ah dhacdooyinka kala-guurka resonance-ka oo ay keento hirarka elektromagnetic-ka ee ku jira goob birlabeed oo joogto ah. Tan iyo markii daraasadahan la sameeyay 1946, hababka iyo farsamooyinka resonance magnetic nuclear (NMR) si degdeg ah ayaa loo horumariyay oo si ballaaran ayaa loo isticmaalay sababtoo ah waxay si qoto dheer u geli karaan walaxda iyagoon burburin muunadda, waxayna leeyihiin faa'iidooyinka degdega ah, saxnaanta iyo xallinta sare. Maalmahan, waxay ka soo galeen fiisigiska ilaa kiimikada, bayoolajiga, juqraafiga, daaweynta caafimaadka, agabka iyo qaybaha kale, iyagoo door weyn ka ciyaaraya cilmi-baarista sayniska iyo wax soo saarka.

Nidaamkan tijaabada ah ee resonance magnetic nuclear-move-move-ka joogtada ah (CW-NMR) wuxuu ka kooban yahay magnet isku-dhafan oo sare iyo cutub mashiin oo weyn. Magnet joogto ah ayaa loo isticmaalaa in lagu bixiyo goob birlabeed oo aasaasi ah oo ay ku dul saaran tahay goob koronto-dhaliye oo la hagaajin karo, oo ay soo saaraan labo gariiradood, si loogu oggolaado hagaajin fiican oo ku timaadda guud ahaan goobta birlabeed iyo in lagu magdhabo isbeddellada goobta birlabeed ee ay keento kala duwanaanshaha heerkulka.

Maadaama koronto yar oo birlabeed ah loo baahan yahay oo keliya goob koronto oo hooseeya, dhibaatada kuleylinta nidaamka waa la yareeyaa. Sidaas darteed, nidaamka waxaa si joogto ah loo shaqeyn karaa dhowr saacadood. Waa qalab tijaabo ah oo ku habboon shaybaarrada fiisigiska ee horumarsan.

Tijaabo

1. In la daawado ifafaalaha resonance magnetic (NMR) ee nucleus-ka haydarojiin ee biyaha iyo in la barbar dhigo saameynta aayoonada paramagnetic;

2. Si loo cabbiro xuduudaha nuclei-ga haydarojiin iyo nuclei-ga fluorine, sida saamiga magnetic-ga wareegga, Lande g factor, iwm.
