Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.

Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Use water spray, dry chemical, carbon dioxide, or appropriate foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from moisture. Store protected from light.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.
Exposure Limits CAS# 7790-29-6: Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.

碱金属和碘原子之间重组反应的绝对三阶速率常数以及Rb + I + He的测量

摘要：

我们提供了反应Rb + I + He→RBI + He（1）的绝对三阶速率常数的直接测量值，该值通常在碱金属原子和原子碘的复合作用下被考虑。I（5 2 P 3/2）是通过在He流动系统中用RbI重复脉冲辐照生成的，并通过真空uv中在λ= 178.3 nm处的时间分辨原子共振荧光进行监视（I [5 p 4 6 s（2 P 3/2）] – I [5 p 5（2 P 3/2）]}使用光子计数。Rb（5 2 S 1/2）使用相敏检测在λ= 421 nm [Rb（6 2 P J）–Rb（5 2 S 1/2）]处通过原子共振荧光以稳态模式进行监测。这些测量结果得出k 1（T = 540 K）=（3.34±0.67）×10 –31 cm 6原子–2 s –1的值。我们还报告了k 3（T = 540 K）= 4.1×10 –10 cm 3分子的反应I（5 2 P 3/2）+ Rb 2 →RbI + I（3）的速率常数的估计–

using phase-sensitive detection. These measurements yield the value of k1(T= 540 K)=(3.34 ± 0.67)× 10–31 cm6 atom–2 s–1. We also report an estimate of the rate constant for the reaction I(5 2P3/2)+ Rb2→ RbI + I (3) of k3(T= 540 K)= 4.1 × 10–10 cm3 molecule–1 s–1, in accord with previous measurements for Br + K2 derived from molecular beams. The recombination reaction was modelled using trajectory calculations
