Singlet: Hauv NMR spectroscopy, cim uas tsis sib cais ; i.e. yog ib kab. Ib tug zoo tagnrho singlet. Ib tug zoo tagnrho doublet. Ib tug zoo tagnrho triplet. Qhov no simulated 1 H-NMR spectrum ntawm 2-ethylphenol suav nrog ntau qhov sib txawv ntawm 6.6-7.2 ppm, ib leeg ntawm 6.0 ppm, ib lub quartet ntawm 2.4 ppm, thiab triplet ntawm 1.2 ppm.

Yuav ua li cas koj tuaj yeem qhia tus singlet doublet triplet?

Yog tias tsis muaj hydrogens ntawm cov atoms uas nyob ib sab, ces lub resonance yuav nyob twj ywm ib qho ncov, ib lub singlet. Yog tias muaj ib qho hydrogen ntawm cov atoms uas nyob ib sab, lub resonance yuav muab faib ua ob lub ncov ntawm qhov sib npaug, ob npaug.

Dab tsi yog singlet doublet triplet?

Vim li ntawd, tsuas muaj ib kab spectral ntawm ib lub xeev singlet xwb. Nyob rau hauv sib piv, ib tug doublet lub xeev muaj ib tug unpaired electron thiab qhia splitting ntawm spectral kab rau hauv ib tug doublet; thiab lub xeev triplet muaj ob qho tsis muaj hluav taws xobthiab qhia peb zaug sib cais ntawm cov kab spectral.

Dab tsi yog doublet ntawm doublet hauv NMR?

Ib tug doublet ntawm doublets (dd) tshwm sim thaum ib tug hydrogen atom yog ua ke rau ob tsis sib npaug hydrogens Ib qho piv txwv yog NMR spectrum ntawm methyl acrylate. … Muaj plaub qhov sib txawv vim Hc yog ua ke rau ob qho tib si Ha thiab Hb, tab sis muaj qhov sib txuas sib txawv rau txhua qhov. Qhov tshwm sim yog ob npaug ntawm doublets.

triplet hauv NMR yog dab tsi?

Triplet: Hauv NMR spectroscopy, ib lub teeb liab sib cais muaj peb kab, kaw ua ke. Qhov siab ntawm cov kab yuav nyob ze rau qhov piv ntawm 1: 2: 1.
