    Shear phenomena in the infrared dielectric response of a monoclinic crystal are shown to unveil a new polariton class termed hyperbolic shear polariton that can emerge in any low-symmetry monoclinic or triclinic system.

    Experimental measurements of vibrational sum-frequency generation spectra indicate that the dielectric response of water near an electrode may be strongly asymmetric, with different responses to positive and negative electrode charge.

    A vibrational spectroscopy technique that measures the electric field emitted from organic molecules following infrared illumination allows their molecular fingerprints to be separated from the excitation background, even in complex biological samples.

    Combining cavity-enhanced direct frequency comb spectroscopy with buffer gas cooling enables rapid collection of well-resolved infrared spectra for molecules such as nitromethane, naphthalene and adamantane, confirming the value of the combined approach for studying much larger and more complex molecules than have been probed so far.
