This work aims to study the hydrogen bond energy and distance for different samples of alfa fibers treated with thymol. The treatment duration and thymol concentration were varied and seem to have a great influence on infrared band intensities and positions. The number of hydrogen bonds is related to the infrared band intensity, whereas their energy and distance depend on the infrared band position.

It was proven that the free hydroxyl groups are weakened and tend to disappear with fiber treatment. It is the same for intermolecular hydrogen bands between cellulosic chains that present a decrease in both intensity and frequency.

The two intramolecular hydrogen bands increase in intensity but exhibit different behaviors regarding the calculated energy: while the band at 3268 cm⁻¹ is weakened and shifted to higher wavenumbers, that at 3338 cm⁻¹ keeps the same peak position and energy.

这项工作旨在研究百里香酚处理的不同α纤维样品的氢键能和距离。治疗时间和百里酚浓度各不相同，似乎对红外波段的强度和位置有很大的影响。氢键的数量与红外波段的强度有关，而氢键的能量和距离取决于红外波段的位置。

已经证明，通过纤维处理，游离羟基被削弱并且趋于消失。纤维素链之间的分子间氢带的强度和频率均降低，这是相同的。

两个分子内氢带的强度增加，但在计算出的能量方面表现出不同的行为：虽然3268 cm ^-1处的能带减弱并移至更高的波数，但3338 cm ^{-1处的能带}保持相同的峰值位置和能量。
