通过求解含时薛定谔方程的数值方法，研究了不同分子构型的平面分子H32+的高次谐波产生，结果表明：奇偶谐波同时释放，且奇偶谐波的相对产量对取向角和分子构型都很灵敏。基于上述结果，提出了利用奇偶高次谐波谱探测原子核位置的简单方法，从而可以通过奇偶高次谐波谱重构取向不对称平面分子的键长和键角，同时利用高次谐波谱为阿秒尺度探测多中心分子结构提供帮助。

The generation of high-order harmonics from planar molecules H32+ with different molecular configurations is studied using the numerical solution of the time-dependent Schr?dinger equation. The results show that planar molecules H32+ emit both odd and even harmonics, and the relative yields of odd and even harmonics are sensitive to orientation angles and molecular configuration. A simple method is proposed, based on the above results, to detect the position of atomic nucleus via odd and even high-order harmonic spectra. Bond lengths and angles from oriented asymmetric planar molecules can be reconstructed using odd-even harmonics at different angles. Meanwhile, probing the polycentric molecular structure in attoseconds using a high-order harmonic spectrum is helpful.
