    Loeb wrote an opinion critical of the nitrogen hypothesis:

    Was the Interstellar Object 'Oumuamua a Nitrogen Iceberg?

    It is true that Spitzer would not see Nitrogen if it was there because of its shorter wavelength. The absence of spin evolution is a serious constraint. Perhaps some support for the Nitrogen hypothesis may be found if a UV telescope can find some trace of Nitrogen along the trajectory allowing for adjustments due to solar pressure and wind since 2017-2018.
