当DNA被紫外光照射时，在胸腺嘧啶碱基中形成顺磁性损伤中心。这种自由基的结构已由电子自旋共振测定，由6号碳位置上的氢加成组成。自由基的形成速率被水蒸气增强，并且它被结合到DNA的顺磁性离子淬灭。
When DNA is irradiated by ultra-violet light a paramagnetic damage center is formed in the thymine bases. The structure of this free radical has been determined by electron spin resonance and consists of a hydrogen addition at the carbon No. 6 position. The rate of formation of the radical is enhanced by water vapor, and it is quenched by paramagnetic ions bound to the DNA.
