چکیده انگلیسی
The Raman spectra of two kinds of expansins KT-30 and DA-6 are measured and analyzed in the cases of pure solid-phase and in water solutions. The results show that, KT-30 has much richer and narrower Raman spectral peaks. The first, second, and third strong Raman peaks are respectively located 990.68738â¯cmâ1, 1606.0975â¯cmâ1, and 1327.9379â¯cmâ1. Besides the dense and narrow Raman peaks below 1800â¯cmâ1, there exist three weak peaks within 3050-3410â¯cmâ1. In comparison, fewer spectral peaks can be observed for DA-6. The first and second strong peaks respectively appear at 2883.03760â¯cmâ1 and 2848.4480â¯cmâ1. There exist about 8 peaks below 1500â¯cmâ1. In water solutions, bell-shaped and homogeneous fluorescence background will respectively superpose on the Raman spectra of KT-30 and DA-6 within 100-2500â¯cmâ1 and 400-4000â¯cmâ1. Parts of spectral peaks will be covered accordingly. Moreover, the peak position shifts of KT-30 are very slight. While DA-6 takes the opposite. Its largest shift can even be up to 63.4148â¯cmâ1. The results can supply important fingerprint data for Raman detection of expansins in fruits and vegetables.
