Nuclei in a fluid subjected to a continuous wave circularly polarized light beam are predicted to experience a static magnetic field proportional to E(+/-) x E(+/-), where E(+/-) is the electric vector of the right or left circularly polarized wave and the dot denotes a time derivative. The field strongly depends on the local electronic structure and is present in all atoms. For an intensity of 10 watts per square centimeter propagating in the direction of the field of a magnetic resonance spectrometer, the general theory presented here predicts shifts of +/- 4 x 10(-8) hertz for protons and +/- 10(-5) hertz for fluorine-19. Larger shifts are predicted if the laser frequency is near an optical absorption.
在连续波圆偏振光照射下的流体中的核，预计将经历一个与 E(+/-) x E(+/-)成正比的静态磁场，其中 E(+/-)是右或左旋圆偏振波的电矢量，点表示时间导数。该场强烈依赖于局部电子结构，存在于所有原子中。对于以磁共振谱仪磁场方向传播的每平方厘米 10 瓦的强度，这里提出的一般理论预测质子的 +/- 4 x 10(-8)赫兹的位移和氟-19 的 +/- 10(-5)赫兹的位移。如果激光频率接近光吸收，则会预测到更大的位移。
