    Characterization of water distribution in cut tobacco using a low-field 1H NMR technique

    MA Ji; HA Baojiang; LI Peng; GUO Xueke; SUN Shihao; YANG Chunqiang; LI Yanqiang; ZONG Yongli; QU Zhan
    Zhengzhou Tobacco Research Institute of CNTC, Zhengzhou, Henan, China
    Cut tobacco was studied by low-field 1H NMR at various water contents and temperatures. The spin-spin relaxation times (T2) were measured with Carr-Purcell-Meiboom-Gill (CPMG) sequences. Three populations were observed in cut tobacco, namely, population ...
