自旋晶格弛豫时间已用于根据所得焦炭的光学织构的尺寸和形状来表征母体可碳化材料，以预测光学织构。自旋晶格弛豫时间值小于 300 ms 的材料产生各向同性或各向异性的焦炭；值在 300 至 600 ms 之间时，可产生具有精细马赛克光学纹理的焦炭；值在 500 到 800 ms 之间时会产生粗糙马赛克的光学纹理；值大于 800 ms 时，会产生表现出流动型各向异性的焦炭。
Spin-lattice relaxation times have been used to characterize parent carbonizable material in terms of the size and shape of optical texture of the resultant coke, in order to predict optical texture. Materials with values of spin-lattice relaxation time less than 300 ms produce cokes which are either isotropic or anisotropic; with values between 300 and 600 ms produce cokes with optical texture of fine mosaics; with values between 500 and 800 ms produce optical texture of coarse mosaic; and with values greater than 800 ms produce cokes which exhibit flow-type anisotropy.
