LED illumination lights

ILLUMINATE SF™ shines a light on San Francisco's ever-expanding light art scene and celebrates the city's culture of creativity and innovation. The initiative is presented by the San Francisco Travel Association in collaboration with local civic and cultural partners, and showcases the city's public light art installations, most of which are accessible by public transportation and free to view.

Home to luxurious hotels and inspiring museums, SoMa also contains some of San Francisco's largest and most ambitious light art.

From the day after Thanksgiving until the end of January, dozens of site-specific artworks by acclaimed creators from all over the world will be on display across San Francisco's many neighborhoods. Some are permanent fixtures that have become familiar icons of the city. Others are fleeting, one-time-only creations that dazzle visitors with their complexity. Best of all, most of these artworks are free to experience.

The rotational spectrum of the van der Waals complex CH4–CO has been measured with the intracavity OROTRON jet spectrometer in the frequency range of 110–145 GHz. Newly observed and assigned transitions belong to the K = 2–1 subband correlating with the rotationless jCH4 = 0 ground state and the K = 2–1 and K = 0–1 subbands correlating with the jCH4 = 2 excited state of free methane. The (approximate) quantum number K is the projection of the total angular momentum J on the intermolecular axis. The new data were analyzed together with the known millimeter-wave and microwave transitions in order to determine the molecular parameters of the CH4–CO complex. Accompanying ab initio calculations of the intermolecular potential energy surface (PES) of CH4–CO have been carried out at the explicitly correlated coupled cluster level of theory with single, double, and perturbative triple excitations [CCSD(T)-F12a] and an augmented correlation-consistent triple zeta (aVTZ) basis set. The global minimum of the five-dimensional PES corresponds to an approximately T-shaped structure with the CH4 face closest to the CO subunit and binding energy De = 177.82 cm−1. The bound rovibrational levels of the CH4–CO complex were calculated for total angular momentum J = 0–6 on this intermolecular potential surface and compared with the experimental results. The calculated dissociation energies D0 are 91.32, 94.46, and 104.21 cm−1 for A (jCH4 = 0), F (jCH4 = 1), and E (jCH4 = 2) nuclear spin modifications of CH4–CO, respectively.
