QSO 光谱通常通过用已知的搜索线识别观察到的线来解释，并且基于这种识别来确定红移。三个 QSO，即。近年来报道了SDSS 1533-00、PG 1407+265和PKS 0637-752，它们的光谱是不寻常的，因为它们不能根据红移假说中观察到的谱线的通常解释来解释。最近的一篇论文（D Basu 和 S Haque-Copilah 2001 Physica Scripta 63 425）表明，QSO 光谱可以用蓝移进行令人信服的解释。由于观测线的错误识别，红移可能已被分配给某些 QSO，因此在这方面应特别研究不寻常的光谱。在本文中，我们根据蓝移确定了上述三种 QSO 在较长波长下光谱中观察到的所有特征。
QSO spectra are usually explained by identifying the observed lines with known search lines and the redshift is determined based on such identifications. Three QSOs, viz. SDSS 1533-00, PG 1407+265 and PKS 0637-752, have been reported in recent years whose spectra are unusual in the sense that they cannot be explained on the basis of the usual interpretation of the observed lines in the redshift hypothesis. In a recent paper (D Basu and S Haque-Copilah 2001 Physica Scripta 63 425), it was shown that QSO spectra can be interpreted convincingly in terms of blueshifts. Redshifts may have been assigned to some QSOs due to misidentification of observed lines, and unusual spectra should be particularly investigated in this respect. In this paper we have identified all the observed features in the spectra of the above three QSOs at longer wavelengths in terms of blueshifts.
