阻抗谱(IS)是一个通用术语，它包括对感兴趣材料(包括电极效应)的线性电响应的小信号测量和随后的响应分析，以产生有关系统物理化学性质的有用信息。分析通常在频域中进行，尽管有时在时间域中进行测量，然后将傅里叶变换到频域。IS绝不限于在阻抗水平(例如，阻抗与频率的关系)上测量和分析数据，而可能涉及四个基本导纳水平中的任何一个：因此，最一般地，IS代表导纳光谱。
Impedance spectroscopy (IS) is a general term that subsumes the small-signal measurement of the linear electrical response of a material of interest (including electrode effects) and the subsequent analysis of the response to yield useful information about the physicochemical properties of the system. Analysis is generally carried out in the frequency domain, although measurements are sometimes made in the time domain and then Fourier transformed to the frequency domain. IS is by no means limited to the measurement and analysis of data at the impedance level (e.g., impedance vs. frequency) but may involve any of the four basic immittance levels: thus, most generally, IS stands for immittance spectroscopy.
