Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Shigewa: Siffar ɗaukar hoto na pyridine a cikin hexane ya ƙunshi nau'i uku a tsawon zango na 195 nm (π → π * miƙa mulki, molar absorptivity ε = 7500 L·mol−1·cm−1), 251 nm (π → π * miƙa mulki, ε = 2000 L·mol−1·cm−1) da kuma 270 nm (n → π * miƙa mulki, ε = 450 L·mol−1·cm−1). Hanyoyin 1H na nukiliya na nukiliya (NMR) na pyridine yana dauke da sigina uku tare da ma'auni mai mahimmanci na 2: 1: 2 wanda ya dace da protons uku daban-daban a cikin kwayoyin. Wadannan sakonni sun samo asali ne daga α-protons (matsayi 2 da 6, canjin sinadarai 8.5 ppm), γ-proton (matsayi 4, 7.5 ppm) da β-protons (matsayi 3 da 5, 7.1 ppm). Da carbon analog na pyridine, benzene, yana da kawai daya proton siginar a 7.27 ppm. Babban canjin sinadarai na α- da γ-protons idan aka kwatanta da benzene sakamakon ƙananan ƙarancin lantarki a cikin α- da γ-positions, wanda za'a iya samu daga tsarin resonance. Yanayin ya yi kama da yanayin 13C NMR na pyridine da benzene: pyridine yana nuna sau uku a δ(α-C) = 150 ppm, δ(β-C) = 124 ppm da δ(γ-C) = 136 ppm, yayin da benzene yana da layi daya a 129 ppm. Dukkanin canje-canje an ambaci su don abubuwan da ba su da ƙwayoyin cuta. Ana gano pyridine ta al'ada ta hanyar gas chromatography da hanyoyin ƙididdigar taro.  Tambaya: Ta yaya mutane da yawa makada suna kunshe a cikin wani pyridine bakan cikin wani hexane?
