Light-driven molecular rotary motors are nanometric machines able to convert light into unidirectional motions. Several types of molecular motors have been developed to better respond to light stimuli, opening new avenues for developing smart materials ranging from nanomedicine to robotics. They have great importance in the scientific research across various disciplines, but a detailed comprehension of the underlying ultrafast photophysics immediately after photo-excitation, that is, Franck-Condon region characterization, is not fully achieved yet.

Background: This study aims to address the lack of substantial evidence regarding the effect of COVID-19 on maternal and child health (MCH) services in India and also highlight the role of primary care physicians in maintaining essential services during a pandemic. While studies conducted worldwide and in India have examined the effects of COVID-19 on these services, a significant gap in robust evidence remains.
Methods: Forty-two districts were selected randomly from seven regional states of India.

The S state relaxation dynamics of chlorobenzene (CB), 3-chlorophenol (3-CP), 3-CP·HO, and 2-chlorophenol·HO (2-CP·HO) have been investigated by means of picosecond time-resolved pump-probe spectroscopy in a state-specific manner. For CB, the S state relaxes via the S-S internal conversion in the low internal energy region (<2000 cm), whereas the direct C-Cl bond dissociation channel mediated by the upper-lying repulsive πσ* state is opened to give the rather sharp increase of the S relaxation rate in the high internal energy region (>2000 cm). A similar dynamic feature has been observed for 3-CP in terms of the lifetime behavior with an increase in the S internal energy, suggesting that the H atom tunneling dissociation reaction from OH might contribute less compared to the internal conversion, although it is not clear at the present time whether or not the sharp increase of the S relaxation rate in the high internal energy region of 3-CP (>1500 cm) is entirely due to that of the internal conversion.
