Existence of linear polarization, formed by anisotropic scattering in the photosphere, has been demonstrated observationally as well as theoretically and is called second solar spectrum (SSS). The SSS is distinguished by its structure, which is rich in terms of information. In order to analyze the SSS, it is necessary to evaluate the (de)polarizing effect of isotropic collisions between CN solar molecules and electrons or neutral hydrogen atoms. This work is dedicated to calculations of the polarization transfer rates associated with CN–electron isotropic collisions. We show that usual rates serve as a proxy for polarization transfer rates. Then, we take advantage of available usual excitation collisional rates obtained via sophisticated quantum methods in order to derive the polarization transfer rates for the X ²Σ⁺– B ²Σ⁺ (violet) and X ²Σ⁺–A ²Π (red) systems of CN. Our approach is based on the infinite order sudden (IOS) approximation and can be applied for other solar molecules. We discuss the effectiveness of collisions with electrons on the SSS of the CN lines. Our results contribute to reducing the degree of complication in modeling the formation of the SSS of CN.

由光球中的各向异性散射形成的线偏振的存在已在观测和理论上得到证实，被称为第二太阳光谱 (SSS)。SSS的特点是其结构，信息丰富。为了分析 SSS，有必要评估 CN 太阳分子与电子或中性氢原子之间各向同性碰撞的（去）极化效应。这项工作致力于计算与 CN-电子各向同性碰撞相关的极化传输速率。我们表明，通常的速率可以作为极化传输速率的代表。然后，我们利用通过复杂的量子方法获得的可用的通常激发碰撞速率来推导X的极化传输速率 ^{CN 的2} Σ ⁺ – B ² Σ ⁺（紫色）和X ² Σ ⁺ – A ² Π（红色）系统。我们的方法基于无限阶突变 (IOS) 近似，可应用于其他太阳分子。我们讨论了与 CN 线 SSS 上电子碰撞的有效性。我们的结果有助于降低模拟 CN SSS 形成的复杂程度。
