EPR interaction parameters used for the X-band ESEEM simulations for samples 2–5.

Aiso, δA and ηA are respectively the isotropic and anisotropy and asymmetry parameters of the 11B hyperfine coupling tensor, according to the notation given in Eq 2. α, β and γ are the Euler angles, according to notation from Ref. [16], and CQ and ηQ are the 11B nuclear electric quadrupole coupling constant and the EFG asymmetry parameter.

根据公式2所给出的符号规则，Aiso、δA与ηA分别为¹¹B超精细耦合张量的各向同性、各向异性与不对称性参数。根据文献[16]中的符号规定，α、β与γ为欧拉角；CQ与ηQ则分别为¹¹B核电四极耦合常数与电场梯度（Electric Field Gradient, EFG）不对称性参数。
