Optical frequency translation of pulses from a mode‐locked laser is described and demonstrated experimentally. The laser beam is passed through a crystal of LiNbO3 whose refractive index is made to change sinusoidally at the mode‐locked laser rou

Magnetic resonance transitions have been observed among several Zeeman sublevels of the hyperfine states of ${\mathrm{H}}_{2}^{+}$ in magnetic fields from 50 to 115 mG. The following $g$-factor ratios $\frac{g(K{F}_{2}F)}{g({K}^{\ensuremath{'}}F_{2}^

Rf transitions characteristic of interaction between the electron spin and the molecular rotation have been observed in para-${\mathrm{H}}_{2}^{+}$. Values of the coupling coefficients ($\ensuremath{\rho}$- type doubling constant) are given for two v

Observations of the 2.6-mm CO line have been obtained along the galactic equator covering longitudes |ℓ| ≤ 3° and velocities |V| ≤ 300 km s^(-1). The strongest emission is concentrated toward the center (|ℓ| < 1°.5) and at low velocities (

A preliminary CO emission line survey covering a strip at b = -2' from ℓ = 359°.7 to ℓ = 2°.8 is presented which shows a continuous band of emission connecting the region between Sgr A and Sgr B. A high-resolution map of the Sgr A cloud near th
