Abstract
We have observed, by low-temperature picosecond spectroscopy, a photo-induced transient at 580 nm in light-adapted bacteriorhodopsin. The transient was characterized by bleaching in the 550-585-nm regions within 6 ps and recovery in approximately 20 ps. The spectral intensity of the transient is found to be enhanced at lower temperatures, and the lifetime slightly elongated.
摘要
我们通过低温皮秒光谱法观察到，在光适应型细菌视紫红质中，于580纳米处存在光诱导瞬态。该瞬态的特征是在6皮秒内550 - 585纳米区域出现漂白，并在约20皮秒内恢复。发现该瞬态的光谱强度在较低温度下增强，且寿命略有延长。
