Gaseous phase hydration properties for thalli of Niebla tigrina from Atacama Desert, and for Umbilicaria antarctica from Isla Robert, maritime Antarctica, were analyzed using ¹H-NMR relaxometry, spectroscopy, and sorption isotherm analysis. The molecular dynamics of residual water was monitored to distinguish the sequential binding very tightly, tightly, and loosely bound water fractions. These two species differ in hydration kinetics faster for Desert N. tigrina [A₁ = 0.51(4); t₁ = 0.51(5) h, t₂ = 15.0(1.9) h; total 0.7 for p/p₀ = 100%], compared to Antarctic U. antarctica [A₁ = 0.082(6), t₁ = 2.4(2) h, t₂ = [26.9(2.7)] h, total 0.6 for p/p₀ = 100%] from humid polar area. The ¹H-NMR measurements distinguish signal from tightly bound water, and two signals from loosely bound water, with different chemical shifts higher for U. antarctica than for N. tigrina. Both lichen species contain different amounts of water-soluble solid fraction. For U. antarctica, the saturation concentration of water soluble solid fraction, c_s = 0.55(9), and the dissolution effect is detected at least up to Δm/m₀ = 0.7, whereas for N. tigrina with the similar saturation concentration, c_s = 053(4), this fraction is detected up to the threshold hydration level equal to ΔM/m₀ = 0.3 only.

^使用1 H-NMR 弛豫法、光谱学和吸附等温线分析分析了来自阿塔卡马沙漠的Niebla tigrina菌体和来自南极洲罗伯特岛的南极洲脐带菌的气相水合特性。监测残留水的分子动力学以区分顺序结合非常紧密、紧密和松散结合的水部分。这两个物种在沙漠N. tigrina的水合动力学上有所不同[ A ₁  = 0.51(4); t ₁  = 0.51(5) h，t ₂  = 15.0(1.9) h；p / p ₀总计 0.7 = 100%]，与 Antarctic U. antarctica [ A ₁  = 0.082(6), t ₁  = 2.4(2) h, t ₂  = [26.9(2.7)] h 相比，p / p ₀  = 100%总计 0.6 ] 来自潮湿的极地地区。¹ H-NMR 测量区分来自紧密结合水的信号和来自松散结合水的两个信号，U. antarctica的化学位移高于N. tigrina。两种地衣物种都含有不同量的水溶性固体部分。对于U. antarctica，水溶性固体组分的饱和浓度，c _s = 0.55(9)，并且溶解效应至少在 Δm / m 0 = _0.7时被检测到 ，而对于具有相似饱和浓度c _{s = 053(4) 的}N. tigrina  ，该分数被检测到阈值水合水平仅等于ΔM/m ₀  = 0.3。
