|photoreaction;[物化]光化反應
光化學反應（Photochemical Reaction）是指物質吸收特定波長的光能（通常是紫外光或可見光）後，其分子中的電子被激發至高能态，從而引發或加速的化學反應。這類反應的本質是光能轉化為化學能，其過程不依賴于溫度，遵循光化學定律（如格羅特斯-德雷珀定律和斯塔克-愛因斯坦光化學當量定律）。以下是詳細解釋：
光吸收與電子激發
分子吸收光子後，電子從基态（S₀）躍遷至激發單重态（S₁）或三重态（T₁）。激發态分子能量升高，鍵角或鍵長改變，反應活性顯著增強。
公式：
$$ text{A} + h u rightarrow text{A}^ $$ （A為基态分子，A為激發态分子，hν為光子能量）

光化學反應（photochemical reaction）是指由光能引發的化學反應，其核心機制是物質吸收光子後發生電子激發狀态改變，從而觸發化學鍵斷裂或形成。以下是詳細解釋：
基本定義與機制
光化學反應是物質吸收特定波長光能後，分子中的電子躍遷至激發态，引發化學結構變化的過程。例如，適鹽細菌利用光驅動質子泵合成ATP的過程就屬于典型的光化學反應。
